I can't fix "BuildPlayerWindow+BuildMethodException: 3 errors"

I'm newbie to making my own games. months ago I created my first project. Once the build is complete, it builds normally.
But now, suddenly I can't build again because of this error

I've been looking for people with the same problem as me. I tried to follow But I can't solve this problem
I did before :
After I encountered a problem I have tried deleting and reinstalling Unity.
I have tried creating a new project. and copy some of the models.
I created an empty projectใ
I tried installing another unity version.
But there is no way to solve this problem...

Unity FileNotFoundException "launcherTemplate.gradle" when building for Android

When using Unity 2021.3.6f1 I get a an error saying launcherTemplate.gradle file cannot be found. I don't see it referenced in the project anywhere.
I tried using a custom gradle file, modify existing gradle files but nothing has done the trick so far.

It looks like it's related to Unity Hub not installing Android build tooling properly.
From https://forum.unity.com/threads/cant-build-quest-game.1307529/
Unity Hub installer neglects to install the tools directory to this path:
c:\Program Files\Unity\Hub\Editor\2021.3.6f1\Editor\Data\Tools\
Copying over the directory from another recent Unity Editor installation will allow one to make Quest/Android builds again.

UnityStandaloneFileBrowser: ArgumentException Mono.WebBrowser is referenced by System.Windows.Forms

I imported the UnityStandaloneFileBrowser asset to a sample project to test it. Unfortunately I am not able to build the project for Windows.
I needed to set the Scripting Backend to IL2CPP and tried to use .NET Standard 2.0 and .NET 4.X, but both gave me these errors while trying to build:
1. ArgumentException

Has anyone an idea, what I can do to fix this?
I contacted the asset developer a few times, but I don't get a response. So you are my last hope :-)

Xamarin Binding "Wrapper type '' is missing its native ObjectiveC Class

I am trying to bind an external accessory MSR SDK to Xamarin. Note, this is ON the device. It does not work in the simulator at all. I keep getting this error:
Wrapper type 'iMagProII.IMag' is missing its native ObjectiveC class 'IMag'.
Here is my .cs with my linker flags:
[assembly: LinkWith ("libiMagSDK.a", LinkTarget = LinkTarget.ArmV6 | LinkTarget.ArmV7 | LinkTarget.Simulator, SmartLink = true, ForceLoad = true, IsCxx = true, Frameworks = "CoreGraphics ExternalAccessory", LinkerFlags="-lsqlite3.0 -lc++")]

Any help on getting this library bound would be greatly appreciated. I have been banging my head at it for hours now.

This occurs when the class IMag can't be found in the final executable.
The most common reasons for this are:
A typo in the class name.
The native library does not include the architecture you're building for. For instance the native library needs to contain i386 code to run in the simulator. You can use the lipo tool to list the architectures in the native library:
$ lipo -info /path/to/libiMagSDK.a
You also need to know the architecture you're using for the app, you can check this in the project's iOS Build settings, on the Advanced page. Select one that the native library includes.
The native library in the binding project depends on another native library which is not in the binding project (and the IMag class is in that other library). All non-platform dependencies must be included.
The native library is incorrectly built, and doesn't include the class you're trying to bind (this is not frequent, but I've still seen it several times). You can use the nm tool to check what's included in a native library:
$ nm -arch armv7 /path/to/libiMagSDK.a | grep IMag
0x0000f00d S _OBJC_CLASS_$_IMag
[other results]
The above result would indicate that the class is included in the native library.

How to debug a Mono project that builds but can't run?

How do I debug a mono project? I can't seem to run it. It builds perfectly. But running it is another issue altogether.
This is the output from running it.

Clearly the mString member contains a garbage pointer. Judging from the call stack, you'll need help from the SubversionSharp team. Or find out somehow why it is trying to handle a Subversion error.
The last post at their web site dates from 2006, "We're not dead!". Their forum server looks pretty dead to me though. Good luck.
