Application: plasmashell (5.27.10)

Qt Version: 5.15.3
Frameworks Version: 5.104.0
Operating System: Linux 6.5.0-15-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04.3 LTS
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
When I connect an external monitor to my laptop, plasmashell almost always crashes.
Disconnecting from an external monitor doesn't show any problem.
I should add that I'm using Ubuntu 22.04 with `kubuntu-backports-extra` ppa

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
