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 > Screen Edges.
I think this has something to do with KWin as well since I had to recompile KWin from source before the KDE Crash Handler said that my backtrace was useful.

I also think that this crash is related to the previous bug report which I reported.

The crash can be reproduced every time.

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