Failed to intialize video: required graphics API functionality not found. Your GPU may not be supported

Hello, I keep getting that error after updating my graphics card.
I tried reinstalling OBS and reinstalling the graphics card, but it didn't help.
(I succeeded once by updating Windows, but after that it doesn't work again)
This is my log from appdata. Please help if you know the solution

Probably, you need to install driver for your new video card. Look for a driver on the site of the manufacturer of the video card or directly from chip maker (NVIDIA, AMD etc).

Did you get this working? I have a Dell laptop with NVIDIA RTX 3060. OBS used to work before updating Windows. I have checked that I have the latest drivers but still have the same issue.

I have this problem as well. I have a Dell XPS 17 9720, and the Nvdia driver is updated. Getting this same error.
