Application: systemsettings5 (5.23.5)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.15.18-200.fc35.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 35 (KDE Plasma)
DrKonqi: 5.23.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
1. From KRunner: open Fonts
2. Select Defaults button and Apply
3. Select Adjust All Fonts and leave it open
4. From KRunner: open (for example) Display Configuration
5. Observe crash

- Unusual behavior I noticed:
Reverting all font settings in KCM Fonts to default made them for some reason much tinier than the default settings should be. Display scaling set to 125%.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemoppsett (systemsettings5), signal: Aborted
