Thanks for this report. This is strange...

This says that the versions of ipython and qtconsole that spyder has
loaded are versions 7.28.0 and 5.1.1 respectively.

And I think we have the problem: you have locally installed versions
of several of the required Python packages (presumably using "pip3
install --user", and these are loaded in preference to the system
versions.
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
