After blast pit I was going down the ladder and the game kept crashing after loading c1a4e. Turns out if I look towards the wall it would crash, but if I look outwards from the ladder it wouldn’t. Now that I managed to get down and swim out backwards I still can’t continue because everytime I turn around it would crash. Don’t really want to play the entire level in reverse.
I now tried to lower all graphic settings to lowest which seems to have helped. Then I set them back to their previous value one by one and it worked. Seems to be an issue with the graphics settings when the level is loaded or something like that
