Error when running a .exe file using Python multiprocessing

Question

I recently dabbled with multiprocessing in one of my python projects.

I would run my script in my terminal and everything would run flawlessly. However, when I turned the .py script into a .exe using pyinstaller it wouldn't work anymore.

I've narrowed it down to the issue being the Manager() method.

Consider the following piece of code:

from multiprocessing import Manager

if __name__ == '__main__':
    print("Starting")
    manager = Manager()
    print("Worked")

Running the script as a .py file outputs:
> Starting
> Worked

After converting to a .exe the script outputs Starting continuously:
> Starting
> Starting
> Starting
etc...

I managed to snatch this error code after performing a keyboardinterrupt on the running code if any help.

Please let me know if you guys encounter the same issue, or have any idea how to fix this. Have a great weekend <3

Thank you so much g.d.d.c all I had to do was
import an extra method
and add an extra command
The code now looks like this:

from multiprocessing import Manager, freeze_support

if __name__ == '__main__':
    freeze_support()
    print("Starting")
    manager = Manager()
    print("Worked")
