every time when I try to join a multiplayer game, or a co-op game, or even try to watch a replay, the game queues normally and then goes to a black screen with only the mouse visible. The game works fine (menus, start-up, searching, etc.) up to the point of an actually game starting. Audio plays in the background as normal.

Game has been working just fine for about 6 months, then today after trying to watch a replay after a game this problem suddenly started. Googling has very little up-to-date information, mostly related to black screen on game start-up during the WoL era. Display is pretty current, updated to the newest nvidia drivers about two months ago.
