Thanks for the hint to https://github.com/OpenPrinting/system-config- printer/issues/176. If this is actually the cause of your problem an updated of the python3-cups (pycups) package should solve the problem. I have synced version 2.0.1 from Debian into Ubuntu Groovy (20.10) now. As soon as it arrives please test.
