Campaign - the siege of acre

Hello !
I have this issue for like a year.
Basically, while in mission, right before the Genoese reinforcements arrive, the game crashes. I’ve tried resetting the game, restarting the mission ( like 3 times ), reloading etc.

Thanks in advance !

My specs:
Ryzen 9 5900x
rtx 3070
32 gb ram ddr4
windows 11

What about re installing the game?
