Fh501

Since the new update for series 31 I can’t launch Forza Horizon 4 because I get error 501. It means that my GPU doesn’t support DX12. However I before this update I could normally play the game. Also when I go to System Configuration it says that I’m using DX12. I’ve also updated my gpu but I still the same problem. I Ryzen 3200g with Vega 8 graphics. I’ve heard that intergated graphics have some problems but I could play the game with no issues before updating Forza. Can someone tell me how to fix this?
