Yes no problem on iPad or Desktop computer in the player.

I don't know how you ended doing this but you have a crazy amount of animation trees in your model. 3492 to be exact. And the workshop is not liking it at all.

It will take you a lot of time if you want to clean it up.
To open the model faster in the workshop, use another language e.g. French - I won't explain why as it is technical and not really useful - otherwise it will take a few minutes in english. Then you will have to delete one by one the 3492 animation trees.

Thanks a lot
and sorry for problems
