Failed to execute Script Main in PYTHON

I have a .exe app that used to work for years in my work’s office. But now, it doesnt open and gives me “Fatal Error- Failed to execute script main”. I sent the file to my home PC, and it opened flawlessly. So I know for a fact that there isn’t any file missing.

I don’t understand why it wouldnt work anymore after 3 years in my work office? I guess something has changed but how to verify? Any tips or workaround? Thanks

both pc’s are Windows 10.
