Plasma freezes after login

Running Fedora 37/KDE/X11, latest update (5.27.6-2).

When I log in to my regular user account, I see the plasma startup 
screen and the rotating gear on a black screen. After several seconds 
(longer than usual), a cursor is displayed and the gear stops rotating, 
but the screen remains blank and is unresponsive. All I can do is power 
off. When I log into a bare-bones account, after about 2 seconds the 
black screen is replaced by the wallpaper and everything looks OK.

I have journalctl logs from the failing login and successful login, but 
I can’t see any errors or tell what the differences are. Are plasma 
errors logged somewhere else?

I had this problem last week and recreated my login account from scratch 
and configured it as I had before, with virtual windows, display 
setting, etc. I was able to log into the newly created account without 
problem. It appears that I made some additional configuration change 
which has triggered this behavior, but I don’t know what it might be.
