Ideas
I am on PC. It also happens randomly when I ADS/right-click. More often than not I can escape it and return to regular play.
I also experience where I sometimes cannot exit the scoreboard screen and I have to restart the game. It seems to happen most often when I am downed while I was ADS. Though, it can happen on any ADS/right-click it seem. When I am permanently stuck in a scoreboard view, I can hit the Esc key to reach another "Menu" scoreboard view. And that's all I can do until I restart the game.
If I play for one hour, three times a week, I will experience the "Escaping" scenario, where I can return to normal play once I die and respawn, at least once for each session. Not usually more than twice a session. I will experience the "Non-Escaping" scenario where I have to kill and restart the game at least once over that week. I sound like a crazy person when I try to describe to my team what is happening. I sympathize with anyone else struggling with this.
