Will is still crash if you start it from console? It has printed a fatal message, which could help finding out what went wrong. But the message came from QtWaylandClient, so it is nothing that I can do here. If you get an error message it's likely that it's actually a Qt or Plasma problem.

Comment 2 lso 2021-02-19 17:15:38 UTC

Well, no crash or startup problems were encountered when the 'kgpg' command was issued on the command line (even with a strace).

As I cannot reproduce the failure at this time, I can't provide any more useful debugging information.  I guess this will have to be closed for now.
