Bug 478194

Application: plasmashell (5.27.9)

Qt Version: 5.15.3
Frameworks Version: 5.104.0
Operating System: Linux 6.2.0-37-generic x86_64
Windowing System: Wayland
Distribution: Ubuntu 22.04.3 LTS
DrKonqi: 5.27.9 [KCrashBackend]

-- Information about the crash:
I've configured display setings so that when connecting to external monitor, main laptop monitor disables. So when plasma is switching working display, it crashes.
Issue not occures when main monitor is not set to be disabled on external monitor connection.

NOTE:
configuration is "built-in display enabled false + save this configuration for only this display arrangement"

The crash can be reproduced every time.

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