I don't know exactly where you're stuck, but have you tried going there at night? When you do, you'll come across a scene where someone is trying to assault a woman, and you can help her. But if you go to the cabin, you'll see that there's nothing you can do. If you sleep and go back in the morning, you'll be able to interact with the cabin.
If you cant find anything, there is a video guide on the discord server
