Because it is like top posting.
Why not?
Please don't "-r".

kwin_wayland seems to object to a missing monitor…

I haven't encountered this issue on KDE 6.4.5; it looks like some kind of regression. My hardware configuration hasn't changed either.

It also reproduces on the LTS kernel.

On X11 session all work fine, as expected. I think it kwin_wayland regression, like cursor on older amd gpu.

Looks like single-gpu, two monitors - what happens if you disable one of the monitors before the suspend?

After disconnect one monitor, kwin_wayland not crash. I try enable coredump and see whats happen with two monitors.

For me 6.5.1 seems to have fixed it. Please confirm.
