Today I updated my system for stable update. After reboot and relogin I cannot reach login screen. The system just show the mouse cursor and a blank screen.

used pacnew for sddm and pacman

WIFI is not working. Can open TTY .screen
Restarted NetworkManager but did not help. Tried to restart SDDM but nothing happens.

Using other system to communicate.
