I've seen a couple of screens that don't let you go "back" [B] even though they're displaying nothing. The main example I have right now is in Samurai > Dojo > Ghost Match > Pickup, it will be searching for a while ... for whatever reason, that's not as important, but I can't "cancel' and just go [B]ack. It happened in Destiny 2 as well, but I can't remember the screen. I have to force quit the game. Seems super silly and bad navigation controls. Maybe I'm doing something wrong ...
