I've just started playing again after not being in the game for a while, jumped onto an existing Crusader and the first 3 or 4 story missions I went through were fine but eventually the game has just started consistently crashing in the middle of fights. Investigation: Martyr Chapter 3, The Secret Weapon, Enter the Inner Sanctum.

It tabs out, gives me the error message I've attached then follows up with the automated report was sent message. I can tab back into the game and it's frozen, then after a minute closes the game.
