pyinstaller .exe build stops right after start with no errors

Question

Im new to the world of algorithms. I created my first NEAT AI using python. This was originally for a school project, but the school doesn't let us install any software on the computers. Therefore, I wanted to make a .exe file from a .py file. I've done this several times, this time it didn't work though. I'm guessing it's because it has NEAT involved. In case anybody is interested, here's the code I use(flappy bird with AI):

When I run the .exe file, the console appears, and shows:

pygame 1.9.6
Hello from the pygame community. https://www.pygame.org/contribute.html

And then stops.

when I run the .py file, it starts the AIs normally and says something like:

******* Running Generation 1 *******

The pyinstaller command I use:

pyinstaller --onefile game.py

I didnt find any solutions to this yet, and I've been browsing for 2 days.

I get no errors when running it from cmd. I also get some "hidden import not found" warnings in pyinstaller while building but I don't think that should be a problem.

I've tried by referencing the /imgs library and config-feedforward.txt but it didn't work that way either. Any help is appreciated. Sorry for any typos or bad english.

Have a nice day!
