Application: systemsettings5 (5.18.4)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-42-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

-- Information about the crash:
I was trying to open the System Settings from the launcher. I have tried multiple times.

I had just restarted my laptop this morning.

There was an NVidia update, and I seem to remember some other issue(s) arising after an NVidia update is applied, before restarting?

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