Hi! Yeah, there was some mistakes in the code on that scene before this updates, but I believe we fixed it this time. Have you tried from this update or the previous ones? Basically it depends if you did the measurements correct or you failed.
The way is coded you need to do both paths to unlock the scene. I'm sorry I wish I knew how to code things better 😔
If you keep having trouble, contact me on discord and I will go through it with you until you unlock it 😀
