Black Screen of Death

I've been playing BF6 on PC for a few weeks now, more often than not the game has been ok - occasional lag in places and other small problems. However, of late the game has been having major problems when running. When trying to quit out of a multiplayer match I often get a black screen and the only way to resolve is to alt+F4 my way out of there and re load the entire game. Today I have also experienced the issue of the game (again in multiplayer) freezing entirely and the sound completely cutting out. I have restarted the game and checked system settings etc, but if this continues I simply can't play online multiplayer BF6. Anyone else had this issue or know of any possible solutions? Really hope this is resolved ASAP.
