DX12 crashing on startup, was working fine this morning

So my game crashed it reset back to dx11 and now every time i change to dx12 the game crashes on startup

i already tried verifying the game files and reinstalling my graphics drivers

doesn’t help, i always get “the game crashed do you want to reset your graphics settings” on startup

is there anything i can delete/reset?
