To reproduce:
1. Open project attached by the user
2. In player settings make sure that scripting backend is set to IL2CPP and code stripping is enabled
3. Build for iOS
4. In build project press on the button
-- Button will activate the Animator which then enters a state that has an animation trying to animate a field on a missing component that is not used anywhere else in the project.

Expected: Nothing should happen after pressing the button
Actual: Build crashes with this stack trace:
