CTD when I load a PVP game

I have been trying to play the beta but every time I load into a pvp match the game crashes to desktop at the same point after I have selected my character but before the match starts.

I have no problem running the game (I don't think, I very new to PC gaming), as I have played a few private bot matches without any trouble. Any ideas on the cause?

Edit: I should also note I was able to play the PS4 beta fine, so I'm pretty sure it isn't network or connection related.

My setup is a G3258 with an R7 370. I am using a AC wireless connection if that might be causing problems (my NAT is Moderate).
