Thanks for this report.

Have a look at the directory ~/.local/lib/python3.9/site-packages to see what's locally installed, and uninstall all of the packages that have newer versions on the system. For example: pip3 uninstall qtconsole iPython I assume that doing this will resolve the problem. If not, please let me know. Best wishes, Julian
