Black screens (darkening) (Elden Ring)

I ran into a very interesting problem. Yesterday I calmly played Elden, everything was fine. Pants full of happiness .....
The next day I go in and see this picture

. The difference between the screenshots is literally a couple of seconds






. The same story ....









And it's not clear what this is connected with.
Shamanized with monitors - did not help
Shamanized with graphics settings - did not help
Checked all the cables - did not help
Restart the game, PC - did not help
Could there be a problem with the hardware? Although the day before that I played and there were no problems. Not a single freeze, bug, crash, etc.
Ps I love when games change beyond recognition in 1 night.
Pss I searched the Internet for a similar problem, but did not find anything.
