Animations in viewport frame only play in studio

I’m helping my friend make a game via team create, but somehow the animations only play in Studio even if my friend uploaded them? The characters are placed in a WorldModel inside a viewport frame, one of my friends told me to try migrating the game into a group same with the animations, but my friend cannot afford one. Is there a possible way to fix this?

You gotta make it a group game so it wouldn’t matter who uploaded it (also upload animations to group)
