Greetings @PahanLp

Welcome to the Unreal Engine Forum! I pulled a post a while back that had this same error. Take a peek here and see if their solution helps fix that for you. [AutomationTool Exited with ExitCode 6](https://forums.unrealengine.com/t/automationtool-exited-with-exitcode-6/274119) Let me know how it goes! Thanks!
