Same problem here on the PS4, game version v220.127.116.1191. We are 130hours or so into the game and while we had that bug occur before it was always solved by quitting and reloading the game, which was annoying enough because of the long loading time of the game. So having this bug now as a permanent issue is kinda game breaking and the solution with the second player leaving and rejoining and passing the controler is far from practical in a game like DOS2 where you often have to change the hotbar/skills. I really hope you have that bug as no. 1 to solve on your list, since it's not a new bug but an old one that now has become really frustrating.
