    • Well no way to debug this, seems your PC has issues since you can't even load Process Monitor and it's the one tool that can tell you what the problem is. Likely your Anti-virus software setting, check it's logs for blockage. Or possibly your IT group has modified your local User Profile and restricted your permissions for dependencies....

      Try a clean PC, if that works then I suggest you wipe your Development PC, be sure to back up everything, and re-install everything, something you have is causing the error.

      Good luck
