SDDM login screen is black, but can type password and login

I have recently had the problem that when I try to login to my PC again after a long period of inactivity, the screen remains black. The mouse pointer is displayed. I can log in by entering the password blind

What could be the reason for this?

On my PC runs ManjaroLinux 24.0.2 Wynsdey

Output of mhwd -l && mhwd -li is:
