Login Screen does not appear after booting

When I log into Manjaro xfce, no login screen appears and it hangs showing Manjaro. Sometimes, when I restart the PC, it shows the login screen and sometimes, it harasses me a lot.

Please help me to resolve the issue.

can you login through a tty (cntrl + alt + F1 to F6) then run startx to start a GUI (not required). then post the output of journalctl --priority=4 --no-pager
