Constant Crashing during Doryani fight

Title speaks for itself. I am playing with 2 others, on PC. When we fight Doryani, during the 2nd phase, the game crashes for all party members. The game completely closes, with no error codes. Is there any way to stop this from happening so we can continue with the campaign? Is there a fix in the works for this? I've seen similar reports about this boss fight crashing the game since as early as December 11th, and still the issue persists.
