This happens to me all the time, but I get stuck turning left or right, round and around. The way to stop it is simply to press whatever keybind direction I have been stuck in (so if I get stuck turning left I press shift-F which is my turn left keybind).
No one I know in game has encountered this. I think this is maybe because I use many movement keybinds, both mouse for general turning and mouse+keyboard for "hard turns" in Warzones when I have to quickly get behind and face a player (scoundrel backblast). Not sure how they can fix it if they don't experiencing it GM side. I'd allow myself to get stuck and submit a ticket to show them if it didn't take them 3 days to answer a ticket
