Application: systemsettings (5.25.0)

Qt Version: 5.15.4
Frameworks Version: 5.95.0
Operating System: Linux 5.18.3-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.25.0 [KCrashBackend]

-- Information about the crash:
After changing the scaling of the display (For X server), my cursor became too big and I am not able to change the size, nor the theme. Except that the cursor does in fact update in differents of the desktop (when hovering over the title bar, or inside specific applications like Firefox, and not the default KDE apps)
When launching the clicking on the "Defaults" button inside the cursor settings of "System settings", the application crash unexpectedly.

I think the bug state appeared when changing the scale of the display under X, and logging in again on Wayland.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
