ImportError: sys.meta_path is None, Python is likely shutting down

Hi, up is my error code, down is how produced it:

#!/bin/python3
import evdev
device = evdev.InputDevice('/dev/input/event3')
def foo():
    print("")

Note that if i remove the foo function it works entirely and i can do all of this in a python console so it won't crash.
My Python version:

3.8.10 (default, Jun 22 2022, 20:18:18) 
[GCC 9.4.0]

Thanks for submitting. I can't reproduce it unfortunately. Python 3.10.5 (main, Jun 6 2022, 18:49:26) [GCC 12.1.0]

I wonder if this exception should be handled in https://github.com/gvalkov/python-evdev/blob/main/evdev/eventio_async.py#L53, just like the RuntimeError

possibly related: https://bugs.python.org/issue44221

there are various random occasions on which people see this error apparently. Also see https://stackoverflow.com/a/69193630

I don't think this should be handled in the try/except. It doesn't look like it causes any harm, seems to be rare and doesn't look like it is specifically related to python-evdev.

Thanks for the quick and detailed answer
One of my friend couldn't reproduce the error either.
I'm also accumulating a lot of random python errors on my side very recently, i guess my installation kinda got corrupted.
So i'll go for a new fresh installation of my coding environment.
