Crash on il2cpp::icalls::mscorlib::System::Threading::WaitHandle::Wait_internal when Player calls Process.HasExited in an IL2CPP build

--

-

Reproduction steps:
1. Open the attached "crash_IN-58386.zip" project
2. Open the "/Assets/Scenes/SampleScene.unity"
3. Build the project with IL2CPP scripting backend ("File" > "Build Settings..." > "Build")
4. Once the build is complete, open the "ProcessIL2CPPCrash.exe" application, located in the build folder
5. Observe the crash

Reproduced with: 2021.3.32f1, 2022.3.13f1, 2023.1.19f1, 2023.2.0b17, 2023.3.0a13

Reproduced on: Windows 11 (10.0.22621) (user's), Windows 10 (22H2)
Not reproduced on: macOS Sonoma 14.0 (Intel)

Notes:

* The Player crashes as soon as "Process.HasExited" or "Process.EnableRaisingEvents = true" is called
* The user found a workaround, which is to use the "kernel32.dll" functions "OpenProcess" and "WaitForSingleObject"

  1. Resolution Note (fix version 7000.0.0a1):

    Process.HasExited is not supported in IL2CPP. It has been changed to throw a PlatformNotSupportedException.
