My model disappears when playing animation

Hi, I was adding a music to my model, it was working perfectly and then for no reason whatsoever the model disappeared both in view mode and in 3D settings. It seems to be stuck in static pose during the second 0, and as soon as it starts playing the whole thing disappears.

Can you provide a link to the model please?

It’s okay I’ve found the problem. I’ve placed 2 scale keys and 2 opacity keys on one of my mesh, and Sketchfab didn’t seem to like that very much ^^ I’ve removed them and replaced them with very close translation keys very far from one another, it did the trick.
