I have found this bug report in arch:
https://bugs.archlinux.org/task/66905
in this bug report the prolem is a python2 library, I have see that the
corresponding python3 library has been updated today:
python3-pyqt5
but I cant try to install the previews version, elsewhere it will remove
calibre and so I cannot test if this is the problem.
Let me know if you need more information or what I can do for try to
understand the problem
Ciao
Davide

Thank you for triaging this issue. It looks like this parent bug
(calibre) was never closed, but that it should have been closed some
time ago. Also, Calibre now uses Python3 and PyQt6 and this bug is no
longer reproducible.

Nicholas
