[Python] When running a Python program on Windows, the program occasionally gets stuck during...

:loop
python.exe run.py
timeout /t 5
goto loop


run.py is stuck at the beginning where the library is imported

import argparse
import warnings
#stuck here
import pytest
def main():

pytest.main(['-s','-v', 'allure-epics=C1'])

if __name__ == "__main__":
main()



The thread hang stack information from the Process Explorer software is as follows. This happened many times, then I used process explorer analysis to find the stuck thread
