Crashing in REDUX mod

[Flak]

Good Morning everyone, so after playing ~8 hours with my friend no problem we had another friend that joined. When he joined he was unable to join due to EU4 crashing itself, then the same thing happened to my first friend. So my first friend hosts and everything goes well until I start getting EXCEPTION_ACCESS_VIOLATION then the became more frequent to the point where I cant even join them anymore due to getting that error and only me. Does anyone know a fix for both of these issues. All of our drivers are up to date and we cant play anymore because of this BC
