My friends Realm won't work

My friend's Realm can be accesed by all my friends except for my, I can enter the realm, but when i get in, i cannot do anything, its like im expectating but my body stays in place, they can hit me and every mob detects me but i move and al my actions dont work and my hitbox stays on spawn. It's like if i was expectating but with my real character stuck on spawn, Hope you let me know what to do soon.
