[2023] [SoP] Game keeps crashing during the quest 'Madness of King Charles'

I am at the boss fight of Siege of Paris DLC. It always crashes while i am in fight with charles the fat. It crashes always after first push to the fire. After the first push, i continue fighting for a while. But then it crashes. It happened four or five times. I loaded old saves to start new but it happened again. I am playing on Xbox Series S and I am on 170th hour in the game. My graphic mode is High Framerate btw. Except this crash, there wasn’t any problem. But because of this i couldn’t end the DLC and turned back to England
