Problems with loading with Kernel 5.12.9

After yesterday update I have a problem to load GUI session with Plasma. As I see, the problem is with the new Kernel version

You haven’t described any problem. What is the image supposed to be telling us? What is the problem loading Plasma? Is it not starting at all? Are there clues to any problems in ~/.xsession-errors?

Plasma doesn’t start at all and I have only a terminal string to login.
I tried some manipulations and currently if I remove Kernel 5.12.9 and stay on 5.12.4, all goes well.
I have no ~/.xsession-errors

Do you use nvidia? seems to be the same thing as this.

The title is not clear there but looks same according to the comments. Added my case.

Looks ok with 5.12.10
