white screen

[76561199434131464]

I just bought seasons dlc, I opened ts4 and clicked load game. it asked me to select a season, and after I did, screen goes white and the game is frozen. I also have ps4 controls (e.g. L2) even though I play on pc. The buttons (like save the gave, menu etc) have weird textures. At first I thought I had broken mods but that's not the case. What do I do?
