This seems like there's some misconfiguration on your system. Qt is crashing at boot.

You can try to run it from a terminal and see the error it's giving, it could give some information.

New crash information added by DrKonqi

plasma-discover (5.12.5) using Qt 5.9.5

- What I was doing when the application crashed: opening discover from system tray for an update after a reboot, caused by an X.org crash.

- Unusual behavior I noticed: X.org crashed after a reboot, I rebooted after my lock screen engaged and broke during an update.
