Bug 430009

Application: systemsettings5 (5.20.4)

Qt Version: 5.15.2
Frameworks Version: 5.76.0
Operating System: Linux 5.9.11-arch2-1 x86_64
Windowing system: X11
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:

I opened Workspace Behavior > Touch Screen.

What I have not mentioned in my previous 2 reports is that prior to all of this, KDE
wouldn't even start properly (it was a mouse pointer on a black screen) and it only
started when I downgraded NVIDIA. After that I noticed no problems except with System Settings.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Bus error
