Simply; if you use a controller on PC and you go to the menu and select Player List, nothing will happen but you won’t be able to move until you reopen the menu and then exit it again.
This can be easily reproduced by entering any place, selecting Start (Options on a dualshock 4 I was using) and Player List.
EDIT: I should add I am using Windows 10 and a Dualshock 4
No output at all. It is as though the Player List is supposed to be showing (so you are still technically in the menu) but you can’t see that ui and you can’t move.
