Why doesn't pyinstall create an exe file?

Question

Python

Good afternoon, I installed the latest version of python, installed via Pip pyinstaller. When trying to convert a file from py to exe, the error "falled to create proccess" came out, I registered the correct path to the python in the path, the error stopped appearing, the program runs, but the file with the .exe extension is not created. On a file in py format, the time of the last modification is changed. how can this situation be resolved?
