Roblox dummy animation support

How do I fix my Roblox dummy that has a waving animation on it? It was working perfectly fine for the last 2 days and now it’s just standing still. I did check the script and everything is the exact same, Any possible solutions to the problem?

Do you own the animation? You can only play animations that is owned under the game’s owner inventory, or group.

And check the animation priority, perhaps another animation overlaps it. AnimationTrack | Roblox Creator Documentation
