Description Joe C 2021-04-16 13:57:28 UTC 
Application: systemsettings5 (5.19.5)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-49-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

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

I used the menu to navigate to System Settings.  It tries to open and crashes immediately.
I also tried to seach for an item in settings like Global Theme or Cursor, which both result in the same crash scenario.

I see there are updates available, but when I click that, it crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted

New crash information added by DrKonqi

systemsettings5 (5.19.5) using Qt 5.14.2

- What I was doing when the application crashed:
I tried opening the system settings app from the application launcher.
- Unusual behavior I noticed:
Window does not open and a notification stating that the app has crashed unexpectedly appears.
- Custom settings of the application:
None that I know of. KDE Plasma has been installed through Ubuntu Packages along with SSDM. I also have Gnome Desktop, XFCE, and Ubuntu with Wayland Desktop installed.
