MulriThreading Error while compilating in exe

Question

After compiling this exe code into a single file, I get this error in the console. When running from the PyCharm project, everything works perfectly.

if __name__ == "__main__":
    freeze_support()

    window.run()

I will be glad to hear solutions to this problem.

I tried another Pyinstaller settings, but it didn't change the result.
