App quits to log in screen specifically on Mojave?

Hey all,

I’m working on an app using python.
App works great even on Sierra and High Sierra, not to mention Catalina.

But specifically on macOS Mojave, whenever I load the “.app” file it quits the system immediately almost to log in screen.

Why would this ever happen?
What special handling does Mojave has that would create such a problem specifically on that OS?
