Split fiction Fatal error

Hello, i am crashing in split fiction on pc after playing a few minutes, sometimes immediately in the main menu. It crashes to desktop with a message" UE split game has crashed, fatal error".

It worked fine until act 3 and the ice king palace, after that it seems to be unplayable. It crashes at the start of cutscenes, sometimes during normal gameplay.

I have tried reinstalling the game, updated my AMD gpu drivers, lowered the graphics settings, tried steam launch options to force dx11, d3d11 and dx12. Nothing is helping and i cant play the game anymore.

Im running 5800x3d, AMD 6950xt, 64gb ram so its plenty for good performance.
