Bug 431388

Application: systemsettings5 (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.10.4-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I have my laptop's internal display and a second external display connected via USB-C. Whenever kscreen2 is started, the internal display is disabled. Upon trying to reactivate it via KDE settings, this crash happens.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
