Operating System: Linux 5.13.0-28-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
It crashes on startup.  I just upgraded some nvidia libs.  

- If the libs make the app unavailable, how about a little warning?

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Aborted
