yesterday i upgraded my system on Archlinux and after a reboot the login screen is back whenever i type the pass, password is right but i think there's some error somewhere dunno. i tried my best to solve it so i switched to tty3 (alt+shift+f3) and ran
and noticed the error it was about symbol lookup error in /usr/lib/libKWaylandServer.so.5 which is a symbolic link to newly install version of this library and when i was doing upgrade it said Warning qt5-* (version) is newer than extra (version).
sudo pacman -Syyu
i used this command to upgrade and it succeed. but everytime i login it throws me back to login screen
