Virtual Production x Steam VR- Get tracked device position and orientation doesn't work!

Hi! So I’m trying to create a virtual production set, and connect my camera to a Vive controller. And it was perfectly working! I used the node Get Tracked device Position and Orientation, and it was all good. So i started adding some assets to my game, just 3d models and all. And now suddenly no matter what i try I’m not getting any tracked data from the Vive controllers anymore. I’ve restarted unreal engine and steam multiple times but it just refuses to work. I’m new to Unreal so i’m not really sure how to debug this. Any help would be greatly appreciated!!
