Did you even read his comments?? It's not a * controller issue. This is a bug that is EXTREMELY common in single player (especially when playing Solveig for some reason) when trying to pick up a new weapon sometimes it just locks you out of being able to do anything, from shoot to melee to aim. You can't do anything. The only way to fix it i've found is to find another weapon and pick it up, then pick up the one you wanted again.
This is nothing to do with the game files, the license, the controller, the network or any other hardware issues. People have been having this issue for ages, on all platforms, with all controller types or KB+M.
This bug is incredibly frequent in the Nordic mission especially, and is so bad i would have refunded the game had i not received it free with Prime.
The number of game breaking or incredibly frustrating bugs in the game is astounding, especially considering they STILL exist despite Dice saying they're not working on BFV anymore.
It's also not "1-1.5 seconds" lmao. it permanently locks your controls until you can "free" them by picking up another weapon, or by dying. The bug happens a lot if you try to pick up weapons and change your equipped weapon quickly, so if you're trying to pick up a new weapon, make sure your weapon swap animations or reload animations have completely finished before you make the swap. The number of animation bugs is ridiculous but at least with this one, trying to make sure animations have finished playing, and you're not switching from primary to secondary (or vica versa) when you pick up a new weapon, will reduce the chance of it bugging out and getting "locked".
