Solved. I was able to run sudo pkcon update and that fixed it. I can log in now but the desktop is rest to system defaults

I updates my distro, kde neon. The login screen changed and now it will not accept my password. I have checked caplocls, numlock, all that. It is the only password i set for it will not take it. I have no other usera on my pc so i cant just login as someone else.

What password is looking for, why is the password i used to login this morning not working?

Summary Distro kde neon Problem logon screen not accepting password
