Happens often that I will be playing a match and the game will either kick me back to the Main Menu or whatever the last game mode launch menu was.

The only way to get back into the match is to kill arena with Task Manager and relaunch the game.
And this will sometimes happen multiple times per match. This has happened in just about every game mode and has been an issue for months. It is very frustrating in general but especially when it happens during a ranked match.
