Commandlet Exits With Code -1073741819 and Exception FPlatformMisc::RequestExitWithStatus(1, 3, WindowsPlatformCrashContext.EngineUnhandledExceptionFilter)Engine exit requested (reason: Win RequestExit; note: exit was already requested)

When a commandlet is run it successfully completes but does not terminate the engine correctly. It appears that multiple requests are made to terminate the engine process these subsequent engine termination requests result in an access violation and a thrown exception.

To avoid this the following can be added to the constuctor of the Commandlet: ```UseCommandletResultAsExitCode = true;
FastExit = true;```

1. Create a Commandlet.
2. Package the project for the Windows platform.
3. Create a powershell script to run the commandlet to enable redirection of the standard output pipe.
4. Add the following to the powershell script
`$process = Start-Process -FilePath <Location_to_Packaged_Build.exe> -ArgumentList “-run=<CommandletName>” -Wait -PassThru -RedirectStandardOutput "log.txt"

Write-Host "Process Exit Code: $($process.ExitCode)"
`
3. Execute the powershell script from within a powershell console.
4. Observe the Commandlet console window appear.
5. Wait for the Commandlet to complete and the console window to be dismissed.
6. Observe the exit code -1073741819 printed in the powershell console window.
6. Open the log file from RedirectStandardOutput location.
7. Observe the WindowsPlatformCrashContext.EngineUnhandledExceptionFilter exception messages in the log file.
