Ballista Bug - Cliff Wolf Temple

Hi all! Apologies if this isn’t the right place to post this. I’ve just started playing the game and I’ve been enjoying it so far. Unfortunately, I hit a snag. The ballista in the Cliff Wolf Temple area refuses to work for me. I can get it to shoot, but I can’t aim it up, only left and right, and it’s stuck pointing down towards the ground. Am I just missing something or is this a bug, and has anyone else experienced something like this in their own gameplay? I can’t progress the quest I’m on without it. ☹️

I’ve tried playing around with the mouse sensitivity options, aim assist, I even tried getting my controller to work with it but for whatever reason the PS5 controller I have doesn’t mesh with the game. Launched the game with and without mods, same result. Totally at a loss right now.
