This error sometimes indicates that you disposed (freed) C# wrappers for native objects still in use. For example, if you dispose an animation instance that is still active, or a viewcontroller from one of its event handlers.

The bad thing about this exception it may not happen instantly after you freed an object. It may take some time app to fail. So, check your app for such situations.
