I have the same problem with few small version differences (for example, I am using Ubuntu 22.04-jammy). When I run anki (same version) on another box running 20.04-focal, this error does not occur.

I think the problem is due to the change in the Qt5 and/or Python versions between 20.04 and 22.04 for the same version of anki, 2.1.15 (442df9d6).

When I get the error described here, the version info is
Anki 2.1.15 (442df9d6) Python 3.10.6 Qt 5.15.3 PyQt 5.15.6

When I find the version info on my 20.04 box, I find
Anki 2.1.15 (442df9d6) Python 3.08.2 Qt 5.12.8 PyQt 5.14.1

Something changed. Are there other apps the need these new versions of Qt and/or Python?

I don't know how many ways this error occurs, but trying to open Tools->Preferences is definitely the main one. I thought I encountered it doing something else, but that doesn't seem to be the case.

I would add that I can work around the problem by using the -X option with ssh to connect from the 22.04 machine to the 20.04 machine.
