Chrome failed to start: crashed in Selenium testing

I am using C# Selenium for automated testing, and after the most recent chromedriver update 89.0.4389.2300, Google chrome starts and crashes right away. The weirdest thing is that when I am running it on my local, everything works fine, but I am also using Azure pipelines to run my tests on a server. The server one gives me this:
OpenQA.Selenium.WebDriverException : unknown error: Chrome failed to start: crashed.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location C:\Program Files (x86)\Google\Chrome\Application\chrome.exe is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
I have googled around and tried things like adding chromeOptions.AddArgument("--no-sandbox") and chromeOptions.AddArguments("disable-dev-shm-usage") but nothing helps. Chrome on my server is updated to the correct version too. The tests run headless.
Anyone else is having this issue?

The error mentions that chromedriver could not bind to open debug port on running Chrome.
Possible cases I met with:
old version of Chrome browser or chromedriver - since some version the port has changed
wrong Chrome binary location (chromedriver is looking for C:\Program Files (x86)\Google\Chrome\Application\chrome.exe)

Chromedriver still only supports version 79 with updated driver

This is most likely a duplicate question, but in my looking around i couldnt find an answer that matches my question exactly.
I am using selenium and NUnit to run unit tests, due to circumstances I have not been working on it for a while, and now that I come back I get this error on all my chrome tests:
OneTimeSetUp: System.InvalidOperationException : session not created: This version of ChromeDriver only supports Chrome version 79 (SessionNotCreated)
I have updated the driver to make sure that wasn't the issue, but even using the version 83 one, I still get this same error.

The ChromeDriver in your Windows %PATH% is likely a different version. The updated driver you downloaded needs to be saved over top of the ChromeDriver in your path.
Open the command prompt
Type where ChromeDriver and press Enter.
Save the updated ChromeDriver in the folder specified in the output of the where command.

You should update the ChromeDriver in your project. It might be done via Tools -> NugetPages.

Selenium Chrome Driver : user data directory is already in use

For this same error there are many questions in Stackoverflow. But none of them solved my problem. So I have to post this again.
My Code:
ChromeOptions options = new ChromeOptions();
options.AddArguments("--disable-gpu");
options.AddArguments("--disable-extensions");
options.AddArgument(#"user-data-dir=C:\Users\myname\AppData\Roaming\Chrome\Profile 6");
options.AddArgument("--profile-directory=Profile 6");
IWebDriver driver = new ChromeDriver(options);
driver.Navigate().GoToUrl("https://google.com");
Initially I was getting an error " Unable to move cache folder, access denied."
then I have added the line options.AddArguments("--disable-gpu"); and the error is gone.
Now my Code is opening the browser with profile : "Profile 6". But after that its throwing the error
Error in the line : IWebDriver driver = new ChromeDriver(options);
"Exception thrown: 'OpenQA.Selenium.WebDriverException' in WebDriver.dll
An unhandled exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll
invalid argument: user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir
"
I have already read almost all topics related to this error. Few of them are :
How to open a Chrome Profile through --user-data-dir argument of Selenium
InvalidArgumentException: Message: invalid argument: user data directory is already in use error using --user-data-dir to start Chrome using Selenium
How to initiate a new Chrome session when the default session is already running using ChromeDriver and Chrome through Selenium and Python
I am stuck in this problem for more than a week now. Please help.
EDIT:
To confirm that I am not using the already opened default user profile, I checked Cheome://version to confirm the user data directory path. Its different than the default.
Also I tried to to run the code after closing all the open chrome instances. This Time I have not received the error. The browser opened by the webdriver. But after that nothing happened. The code got time out error after 60 seconds in the line : IWebDriver driver = new ChromeDriver(options);

Possibly you are specifying the wrong directory. Instead of:
C:\Users\myname\AppData\Roaming\Chrome\Profile 6
You need to pass:
C:\Users\myname\AppData\Local\Chrome\Profile 6
So the effective line of code will be:
options.AddArgument(#"user-data-dir=C:\Users\myname\AppData\Local\Chrome\Profile 6");
Update 1
Additionally, you can remove the argument --profile-directory as in:
options.AddArgument("--profile-directory=Profile 6");
Update 2
If I close all the chrome instances and run the code, I am not getting this error means ChromeDriver is able to open the Chrome browsing instance perfectly. But to analyze why nothing happened can be interpreted from the TRACE level logs.
Ensure that:
JDK is upgraded to current levels JDK 8u251.
Selenium is upgraded to current levels Version 3.141.59.
ChromeDriver is updated to current ChromeDriver v83.0 level.
Chrome is updated to current Chrome Version 83.0 level. (as per ChromeDriver v83.0 release notes)
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test as non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

I was seeing the same issue. The problem only appears when using Chrome 65 (currently: dev channel). With Chrome 64 (both stable channel and beta channel) everything worked fine.
It turns out I had an old chromedriver installed. Specifically, I was using chrome=65.0.3325.51 with chromedriver=2.29.461585. Running npm install -g chromedriver bumped chromedriver to 2.35.528157 and now the problem is solved.
TL;DR: run npm install -g chromedriver

The error says it all :
Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value'

Your main issue is the version compatibility between the binaries you are using as follows :
You are using chromedriver=2.33
Release Notes of chromedriver=2.33 clearly mentions the following :
Supports Chrome v60-62
You are using chrome=65.0
Release Notes of ChromeDriver v2.37 clearly mentions the following :
Supports Chrome v64-66
So there is a clear mismatch between the ChromeDriver version (v2.33) and the Chrome Browser version (v65.0)
Solution
Upgrade ChromeDriver to current ChromeDriver v2.37 level.
Keep Chrome version at Chrome v65.x levels. (as per ChromeDriver v2.37 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
Execute your #Test.

The latest chrome browser requires corresponding latest chromedriver executable for the tests to run.

I have encountered the same issue and installed the chrome drive. Issue got resolved.
npm install chromedriver --chromedriver_version=LATEST

Changing latest version of ChromDriver worked for me.

You may need to update you driver the link for all the chromedriver updates are http://chromedriver.storage.googleapis.com/index.html
make sure you chromedriver corresponds to your version of chrome

I simply installed a new version of Katalon Studio and it has worked fine.

This issue happens when chrome and chromedriver are not in sync. Either update both to the latest version or make sure they can work together. After running the following commands it worked for me
npm install -g chromedriver --chromedriver-force-download
webdriver-manager update

OperaDriver not working

Using Selenium Grid2 and RemoteWebDriver in an MSTest class, I am struggling to get OperaDriver working.
I create the Selenium hub and Opera node by running the following commands in CMD:
start java -jar selenium-server-standalone-2.30.0.jar -role hub
start java -jar selenium-server-standalone-2.30.0.jar -role node -port 7001 -browser "browserName=opera,version=11.62,maxInstances=5,platform=WINDOWS" -hub http://localhost:4444/grid/register
And this works fine, I can the see the registered node when I view my hub in a browser.
But I get an exception whenever I try to create a new WebDriver in my C# test class:
DesiredCapabilities operaCapabilities = DesiredCapabilities.Opera();
operaCapabilities.SetCapability(CapabilityType.BrowserName, "opera");
operaCapabilities.SetCapability(CapabilityType.Platform, "WINDOWS");
operaCapabilities.SetCapability(CapabilityType.Version, "11.62");
operaCapabilities.SetCapability("opera.binary", "C:\\Program Files\\Opera\\opera.exe");
operaCapabilities.SetCapability("opera.port", 7001);
RemoteWebDriver operaDriver = new RemoteWebDriver(operaCapabilities);
Actually I get two different exceptions - the first time after creating the hub and node in Selenium I get this:
Could not find a platform that supports bundled launchers, please set
it manually
Build info: version: '2.30.0', revision: 'dc1ef9c', time: '2013-02-19
00:15:27'
System info: os.name: 'Windows 8', os.arch: 'x86', os.version: '6.2',
java.version: '1.7.0_15'
Driver info: driver.version: OperaDriver
And everytime after that I get the following error:
Could not initialize class
com.opera.core.systems.runner.launcher.OperaLauncherRunner
I am using Selenium-standalone-2.30.0.
I was using Opera version 12.14 but downgraded to 11.62 after I saw a list of compatible versions on the OperaDriver wiki page but the errors remain the same.
I have tried initialising the RemoteWebDriver with and without the capabilities above and get the same result every time.
Does anyone know what the problem is here and how to get a RemoteWebDriver working with Opera in this way?
Edit: Could it be that the platform for Opera version 12.14 reads as 'WINDOWS 8', and version 11.62 reads as "WIN32" when I open the Opera browser and view Help => About? As I am specifying the platform as WINDOWS in the node and RemoteWebDriver. If I try to specify WINDOWS 8 as the platform for the RemoteWebDriver an new exception is thrown where it can't find matching enum:
org.openqa.selenium.WebDriverException:
java.lang.IllegalArgumentException: No enum constant
org.openqa.selenium.Platform.WINDOWS 8
Edit2: For some reason CurrentPlatform is returning Vista for me, even though I am running Windows8.
Platform platform = Platform.CurrentPlatform;
And I also noticed that the OperaDriver source code checks for 'VISTA' in uppercase whereas the Platform in C# reads as 'Vista'.
Could this be causing the problem?

I've been suffering from this problem as well and thanks to the hint from eviltester I was able to solve the issue by using the following command line to start the selenium server:
java -Dos.name=windows -jar selenium-server-standalone-2.32.0.jar
The use of -Dos.name=windows is the equivalent of System.setProperty("os.name", "windows") and will allow your C# selenium code to work for the Opera browser.

I saw this when running in Java. In debug mode it looked like a possible omission in OperaLauncherRunner.java launcherNameForOS does not cater for the WIN8 enum returned by Platform.getCurrent().
In Java I fudged it by setting the system property "os.name" to "windows" before creating a new OperaDriver. This forced the Platform.getCurrent to return XP which the opera launcher was happy with.
So in java I just used this hack:
System.setProperty("os.name","windows");
driver = new OperaDriver();
