On my laptop the keyboard shortcuts magically restored themselves after I logged in and out of X11 and Wayland mode a few times. I'd try that on my desktop if I could get the UI for logging out to spawn :) (or the UI to configure the shortcuts)
> Have you tried setting them up from scratch?
I couldn't summon any UI to set them up (remember that there's no panels or desktop to click and that KDE applications in general have rendering issues that can render them unusable). I suspect it won't help though since when I log in I can see them blinking in and out of existence a few times before disappearing permanently, I assume crashing and restarting a few times before giving up on running.

I do have quite a bit of customizations on top of the default that I'd rather not lose, but I'll set them up again if I have to. After it looks like it will actually work that is.
