If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl? Thanks! Created attachment 159147 [details]
stacktrace of the crash
Thanks for the link - that was helpful, though it downloaded 720 GB of debug symbols.
In addition, I found, I can also crash KWin by forcing a negative (x,y) position, e.g. to "hide" the window decoration by moving them out over the upper left corner off the screen. The setting is stored, but the dialog became invisible - likely it is shifted far off outside the screen and I cannot see it anymore (other than that it darkens the parent and blocks all input) - luckily I could close it by Escape.
A position, that will shift some of the dialog out to the lower right is fine though. Only the upper left corner must stay on screen, while moving a window manually off screen by META+LMB-drag works nicely.
> 720 GB of debug symbols
Wow, I really hope there's a typo there!
Regardless, pasting the backtrace inline for searchability:

Hihi ... you're right - my harddrive is not that big, it has to be 720 MiB not GB ;-) *** This bug has been marked as a duplicate of bug 466380 *** Created attachment 165769 [details]
New crash information added by DrKonqi
kwin_x11 (5.27.10) using Qt 5.15.12
Applying Window Rules where I match window classes and force position to specific activities causes KWin to crash (twice, seemingly – two notifications are displayed).

Created attachment 159042 [details] Screenshot of rules SUMMARY I want my Firefox maximized in both directions and without decorations. STEPS TO REPRODUCE 1. Create window rule for Firefox as in the screenshot 2. Open Firefox: no decorations, but maximized is not enforced properly 3. Open rule definition, e.g. toggle "decorations enforced to no" 4. Hit apply OBSERVED RESULT Kwin crashes and some different window is on top. The Panels and window decorations for other windows reload and you are on desktop one. The Settings-dialog is gone.
