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

I had just started my PC (cold boot) like I have done a couple of times now.

Discord, Steam, Firefox all running by default

The Taskbar is not present (I think that is what has failed) will reboot and try again

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
