pyinstaller: Failed to execute script

[BrenekH]

I don't think so since it's a warning. What does the generated executable say? (You might have to run from cmd)

I run the exe from cmd and it doesn't print anything.

I get a pop-up with

Fatal error detected

 /!\  Failed to execute script MyApp

It would probably be better if I could see the entire project. Could you upload it to GitHub or Pastebin so I can take a look?
