Application: systemsettings5 (5.17.3)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.3.12-arch1-1 x86_64
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:
I opened the System Settings, changed my GTK theme and then tried to change my Window Decorations.
- Unusual behavior I noticed:
System Settings crashed. I also have a major bug with Kwin on X11 crashing on boot (doesn't happen on Wayland) that I have not managed to get logs for. It's not exactly a crash, the windows are all there and i can interact with them but I can't see them until i do "kwin_x11 --replace". Once I restart Kwin, it works perfectly. Could there be any connection between the two issues? If so, is there any way to collect logs for Kwin from boot?

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
