Unable to take screenshots for iOS simulator version 12.4 using Appium

I am using Appium automation tool to automate UI testing for mobile app using C#.
Testing environment:
XCode - 13.2.1
iOS - 12.4
Appium 1.22.3
Appium.WebDriver - 4.3.2
When I run tests in iOS simulator 15.2, I can take screenshots using Appium without any errors. But in iOS simulator 12.4, I am getting error when taking screenshot.
Error is falling in the below line:
Screenshot screenshot = driver.GetScreenshot();
Error I got in visual studio:
OpenQA.Selenium.WebDriverException : The HTTP request to the remote
WebDriver server for URL
http://127.0.0.1:4723/wd/hub/session/575ce7df-ffbb-4b2e-957c-e7eca7829b75/screenshot
timed out after 60 seconds.
----> System.Net.WebException : The operation has timed out.

C# Selenium Chromedriver only shows 'data'

I created a very simple C# project to test Selenium and Chrome Driver, but when I run it, it gets stuck at the very first line, ie. creating ChromeDriver object.
I have set up as following:
.NET Core 3.1 console app (also tried .NET 4.7)
Installed Selenium.WebDriver 3.141.0 and Selenium.WebDriver.ChromeDriver 87.0.4280.8800.
My Chrome version is "Version 87.0.4280.88 (Official Build) (64-bit)". I have double-checked compatibility with Chrome and ChromeDriver.
Code:
using OpenQA.Selenium.Chrome;
namespace MyFirstSelenium
{
class Program
{
static void Main(string[] args)
{
ChromeDriver chrome = new ChromeDriver();
chrome.Navigate().GoToUrl("https://www.google.co.jp/");
}
}
}
visual studio screen
chromedriver.exe is copied to the debug folder as expected, so I assume the problem is neither compatibility nor path.
chromedriver
When I run the code, the result is an empty window with 'data' in the address bar. No error is thrown. I have searched for several hours and found some articles, but most of them are old and none of these answers led to success.
Any help is appreciated. Thank you.
Added chromedriver.exe verbose console output.

New code
Works when I first execute "chromedriver.exe --verbose --log-path=chromedriver.log", but without it, it throws WebDriverException.
OpenQA.Selenium.WebDriverException: 'A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL localhost:9515/session. The status of the exception was UnknownError, and the message was: No connection could be made because the target machine actively refused it. No connection could be made because the target machine actively refused it.'
var chromeOptions = new ChromeOptions();
chromeOptions.BrowserVersion = "87";
IWebDriver driver = new RemoteWebDriver(new Uri("http://localhost:9515"), chromeOptions);

Possibly a classic case of cyclic redundancy.
chrome is a reserved word, you may have to change the variable name to something else e.g. chromex. So your effective line of code will be:
ChromeDriver chromex = new ChromeDriver();
Additional Consideration
Consider the following aspects aswell:
Instead of using the ChromeDriver class use the IWebDriver interface.
IWebDriver driver = new ChromeDriver();
Instead of the partial url google.co.jp/ you need to pass the complete url through GoToUrl() as follows:
driver.Navigate().GoToUrl(#"https://www.google.co.jp/");

C# Appium IsAppInstalled error: Could not find package

The problem
Hello.
I have a class in C# to verify if my app is installed or not in my device.
When my device has the app installed, everything works fine. However, when my device does not have the app installed, the system gives me this error message:
Message:
Test method MYAPP.Main.RunTest.RunAllTests threw exception:
System.InvalidOperationException: An unknown server-side error
occurred while processing the command. Original error: Could not find
package com.android.MyApp on the device
How to use and declare the IsAppInstalled?
I’m using VS 2017 Community.

Chrome opens for a second and the crashes

I'm using Appium and C# in order to run tests on my Galaxy S5.
Everyhting worked perfectly , but last night we have updated the ChromeDriver to 2.25 and suddenly the chrome in my mobile just open the chrome, shows "data:" in the URL and crashes. on the other hand, the chrome in on Windows OS(selenium) works well.
[SetUp]
public void Setup()
{
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.SetCapability("device", "Android");
capabilities.SetCapability("deviceName", "Galaxy S5");
capabilities.SetCapability("newCommandTimeout", "300");
capabilities.SetCapability("platformName", "Android");
capabilities.SetCapability("platformVersion", "6.0.1");
capabilities.SetCapability("appPackage", "com.android.chrome");
capabilities.SetCapability("appActivity", "org.chromium.chrome.browser.ChromeTabbedActivity");
_driver = new AndroidDriver<AppiumWebElement>(new Uri("http://127.0.0.1:4723/wd/hub"), capabilities, TimeSpan.FromSeconds(180));
}
Appium's ERROR:

updating the Appium's chromedriver manually to the latest one fixed the problem for me.
just downlaod the latest chromedriver vsersion and put it in the following path:
C:\Program Files (x86)\Appium\node_modules\appium\node_modules\appium-chromedriver\chromedriver\win

Can't launch chrome driver in Selenium

I was always able to launch chromedriver server locally but then I tried to do this remotely and since then I am unable to launch it. I reinstalled chrome as well the chrome driver but nothing seems to fix this. Even when I give the path of my driver it won't launch.
using OpenQA.Selenium;
using OpenQA.Selenium.Support;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Chrome;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium.Safari;
using OpenQA.Selenium.Interactions;
namespace TestWebDriver
{
class Program
{
static void Main(string[] args)
{
var driver = new ChromeDriver(#"C:\Users\laurens.putseys\Documents\Visual Studio 2015\Projects\TestWebDriver\packages\Selenium.WebDriver.ChromeDriver.2.21.0.0\driver\");
driver.Url = "http://google.be";
Console.ReadLine();
driver.Quit();
}
}
}
The error I get is the following:
An unhandled exception of type 'System.InvalidOperationException' occurred in WebDriver.dll
Additional information: unknown error: chrome failed to start
(Driver info: chromedriver=2.21.371459 (36d3d07f660ff2bc1bf28a75d1cdabed0983e7c4),platform=Windows NT 6.1 SP1 x86_64)
It started after I tried this:
System.Environment.SetEnvironmentVariable("webdriver.chrome.driver",#"/path/to/where/you/ve/put/chromedriver.exe"
Now I cannot launch the local either. Launching IE and Firefox local work without any problems. Any ideas? Thanks in advance!

try downloading the driver and give its path to contractor - LINK
driver = new ChromeDriver(DRIVER_PATH);

By the version number (2.21.371459) you can tell that the ChromeDriver executable has been launched by your remote Selenium server. But the ChromeDriver was obviously unable to launch the Chrome browser. Is it installed on the server? Can you launch is manually? Can you watch the remote server on a screen and see what happens? Are there any error message boxes displayed by Chrome?
Maybe uninstalling and re-installing Chrome could help!

I had the same problem. I had the browser set to always run under the administrator.
So I started Visual Studio as an administrator and the problem was solved.
