Hello, I was suffering the same problem minutes before.

I found in the file /etc/sddm.conf.d/kde_settings.conf, there was nothing after Session=, so I simply changed it to Session=plasma.desktop and fixed it. I don’t know why but it does help.

(I’m not very familiar with the forum and English language. Anyway good luck.)

Before the update, i don’t have this file in /etc/sddm.conf.d; i only have virtualkeyboard.conf…

If i update all packages except sddm and sddm kdm (i don’t try sddm alone), i can connect to the desktop.
The problem is sddm…
