Black screen when opening the game

What is the main reason why the game gives a black screen and doesn't start anymore? I'm experiencing this problem, and I've always played normally. I've tried everything and nothing worked, black screen as soon as I start the game. It doesn't return crash logger or any error in txt.

I use the same settings I've always used and tested with one Modlist which worked until yesterday and I have almost 30 hours of gameplay and a new Modlist that I only used for a few minutes. Black screen in both.

Just to add more information on the possible solution to the problem, I tried to enter the vanilla game, it also gave a black screen.

I use MO2 and try to open FalloutNV.exe without success.
