In past ~3 days some plasma related updates have broken something:
many machines with different FOSS VGA drivers I got a black screen
showing mouse pointer only. Usually after SDDM login, but sometimes even
while kscreenlock is active. The only way to escape from the situation
is to reboot the system.

Yes. If you enable key sequence to kill the webserver then you can
get back to the login screen without having to reboot. I haven't got
around to checking if this has been reported yet.
