Game Crashing every time

Hey y’all, i’ve been trying to solve this problem for a week or so and I’ve decided to ask here to see if this is a known problem. All of my drivers are updated, I don’t have any sub mods enabled, and I’m running on the most recent version of the game. It is becoming quite frustrating. Ever since all under heaven was released, and the subsequent ck3agot patch was released for the mod, every single time I try to start a new game it crashes. Do I need to relaunch the game in a previous version? Or am I being stupid enjoying something wrong

Very much appreciated y’all Ser_Jammy
