Access violation upon joining server

[Richard For Ponies]

Specifically, I've just begun 'trying' to play arma 3 with my friends, and can't, because I repeatedly recieve 'Status_Access_violation' errors anytime the server gets halfway loaded. It lets me into the player lobby, select my role, then click ok to l oad, then it gets half-way, and CTDs.

The weird thing is, when the host changed the map to a simpler VR map last night, it worked, but joining both him and another friend hosting other maps caused this problem again.
