Comment 1 Bug Janitor Service 2022-11-12 08:33:30 UTC 
Thank you for the bug report!

Please note that Plasma 5.25.5 is not supported for much longer by KDE; supported versions are 5.24, and 5.26 or newer.

If at all possible please upgrade to a supported version and verify that the bug is still happening there.

If you're unsure how to do this, contact your distributor about it.
Comment 2 Nate Graham 2022-11-14 21:07:39 UTC 
Something about the new geometry make Qt very unhappy. Unfortunately it's impossible to tell what because these lines in the backtrace are missing debug symbols:

> #39 0x00007f8903fdcc25 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/plugins/kcms/kcm_kscreen.so
> #40 0x00007f892ef0e636 in ?? () from /lib/x86_64-linux-gnu/libKF5KCMUtils.so.5
> #41 0x00007f892ef16535 in KCModuleProxy::load() () from /lib/x86_64-linux-gnu/libKF5KCMUtils.so.5
Could you please use your package manager to install debug symbols for kscreen and frameworks-kcmutils, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!

Sorry, I ended up with a different installation (KDE Neon with additional ubuntu-studio package) which just works fine so I won't be able to reproduce the issue. I'll keep in mind the suggestion for a useful bug report next time.
