While I was playing one of the Summer 2022 campaign maps (14), I accidentally opened up the scoreboard from the pause menu because my mouse was hovering over it. When I did that, the menu closed and my game screen froze, clicking buttons on my keyboard still made sound effects but nothing made my game unfreeze, I restarted the game and did it again to make sure it wasn't a one time thing and my game froze again, so it seems to be a reoccurring issue. I believe this only happens when you open scoreboard from the pause menu.
