Probably the config for the display manager got corrupted.
You need to reboot from SD and try to fix the autologin section.
In the worst scenario it's some Plasma Mobile file that got corrupted and DM falls back to login screen after unsuccessful start of the environment.
This could happen due to unwritten changes to the disk (not flushed from cache)
Each scenario requires a bit of Linux knowledge to diagnose and fix them.
If you lack time/knowledge the easiest solution is a reflash.
