How to reproduce:
1. Open the attached project
2. Open Test scene and select GameObject in hierarchy
3. If it doesn't have Animatorcontroller component attached, attach it
4. Build asset bundles (Test-> BuildAssetBundle-> BuildassetBundle)
5. Delete animator controller from GameObject
6. Play the scene
7. Unity crashes even if Animator controller is loaded from resources folder

Workaround: Delete animator controller form GameObject and rebuild AssetBundles
