How to reproduce:
1. Open the attached project
2. Open Asset Store, download and import Mixamo animation store
3. Open it (Window -> Mixamo Store)
4. Select vincent Character from the project
5. Search for free animation in Select Motion part
6. Pick one of the free animations
7. Preview it, it works
8. Press buy and Asset Store will open, press buy again it will show the page where you can download mixamo animation -> Download it and make it not legacy
9. Move vincent model to the scene
10. Add Controller AnimationController
11. Go to the controller and select that animation in existing states
12. Play the scene -> notice that animations aren't playing

This issue won't be fixed because bindings appear broken for an unknown reason and as mixamo pulled its animations from store, it is impossible to fix this issue.
