Try verifying the integrity of the files, that's what I did and it stopped crashing. It was happening since the last update.
I'm having some issues, I just booted up my savefile for the first time since the last update, and in the next fight half the npcs are invincible and won't die when reaching 0 HP. EDIT: It seems like it only happens in the Drowned Barrows.
