9 months ago I'm getting this stack-tracke after installing the script using pip, running it and selecting my brother MFC9332CDW Printer (which was found).
I'm running ubuntu 22.04 (jammy).

This is a dependency issue where PySNMP needs the PyASN1 implementation in python.
Installing it in pip or your python virtual environment will do the job:
pip install --upgrade pyasn1
