You'll have to explain how that happens in greater detail, please. Also a complete journal might help.

I'm using Arch Linux as my daily drive. I updated my system this morning and rebooted to a black screen. I got into TTY and found out that the /usr/bin/kwin_wayland crashed and Drkonqi crashed too. But the strange is that the SDDM was still running. And every time I tried to restart SDDM, the Drkonqi will crash after kwin_wayland crash.
