Hi Michael Sorry, I am unable to reproduce your bug. I tried to move my documentation but without success.
PyQt6 is version 6.4.2 on my system but 6.4.1 on yours. Can you please try to upgrade it? It migrated to testing on the 13th. Otherwise if python3 -v -v /usr/lib/python3/dist-packages/eric7/eric7_ide.py might give more info. Regards Gudjon
