white screen in the first animus (Assassin's Creed 2)

I downloaded assassin's creed 2 and I start the game at the beginning everything is fine, but when I entered the animus for the first time (where Desmond climbs at the request of Lucy), then my game freezes on a white screen. I downloaded various repacks, files, and much more. I hope that you will help me, if your method works, then I thank you.
