ADDITIONAL INFORMATION

(I also see reports of instability with this update on bodhi: https://bodhi.fedoraproject.org/updates/FEDORA-2025-bf80d1dadc)
Comment 2 mark 2025-03-08 01:13:45 UTC
Also, I downloaded and installed four packages of the previous version, 6.3.2.1-1.fc41 from here: https://koji.fedoraproject.org/koji/buildinfo?buildID=2659658
kwin, kwin-wayland, kwin-common, kwin-libs

And downgraded to them with dnf and none of my steps are causing crashes anymore.

I've been having the same issues, same device and distro.

Just to add another trigger for what is potentially the same crash, exiting from sleep also produces a guaranteed crash. The XWayland Video Bridge also fails to start after these crashes, and attempting to run an X11 application through it will then cause another crash.
