Answer 2

I managed to solve the problem by installing the developer branch package.
A simple solution for those who do not know.
in cmd or powershall :

pip uninstall pyinstaller
pip install https://github.com/pyinstaller/pyinstaller/archive/develop.tar.gz

Everything has been fixed. Used pygame, made a simple toy. Who can help you can thank me with the word "thank you" in the comments :)
