I had a simple backup script (backup-script.py) for a multiple vendor device environment. The script was working fine before and failed after I upgraded my mac OS to Big Sur, 11.0.1.

macOS Big Sur, 11.0.1
Python 3.8.6

Traceback (most recent call last):

Reinstalling pyserial fixed the problem.

pip3 uninstall pyserial
pip3 install pyserial
