I don't think you did anything wrong. Did KWin crash too? Or just System Settings?
Created attachment 138232 [details] attachment-27060-0.html I think all qt based/kde native application crashed simultaniously. I.e. dolphin, yakuake and etc. For KWin, hard to say.

Looks like a KWin crash. You can check this by installing systemd-coredump and reproducing the crash. Then, coredumpctl can be used to fetch a backtrace of kwin_wayland.

I'm sorry, you don't have a useful coredump because I forgot to mention one step. Please edit the file /etc/systemd/coredump.conf the following way: * Find a line like "#ExternalSizeMax=2G". * Replace it with "ExternalSizeMax=6G" (do not include the quote signs). After that, try to make it crash again. Then, run "coredumpctl" again and note the PID column of kwin_wayland (it was 3247 in your example). Run "coredumpctl debug PID" where you replace PID with that number. Then enter "bt" when the GDB prompt appears and copy the backtrace that appears.

You almost got it, but you missed two things: * You need to use "coredumpctl" with the PID of the crash *after* you have made the modification to the config file. * You forgot to enter "bt" into the gdb prompt.
