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

I open my Browser Vivaldi (Chrome-base), when i click in the border to bring the window to the full size of the desktop plasma crashes, and from then on it crashes again after some minutes.
after 3-5 crashes plasme didn't restart anymore. Apropo Any,  I installed Anydesk from Flathub, it refuses to work, when i start it, it did't open the window....
