Horrible red overlay over everything

Now I the first time I booted up the game was yesterday. It crashed. That happened another four or five times. But on attempt five or six, it worked, and I was greeted to this. This horrible red overlay was there on the character creation screen in the prologue and on the boat. If I kept playing passed that point I’m sure it would’ve gone on.

Also, I’m not sure this has anything to do with the red screen but everything was suuuuuuper slow I would put my cursor on the settings button and the game would respond four seconds later.

Please if anyone knows how to fix this please please tell me
