UnityScene::AddRootToScene crashes when importing a Prefab

Animation

-

To reproduce:

1. Download attached “PrefabCrash.zip" project and open in Unity
2. Select "MissionsView_Roots.prefab", right-click it and press "Reimport"

Expected results: Unity Editor successfully imports a Prefab
Actual results: Unity Editor crashes

Notes:
- This issue appears both on Windows and macOS
- Stacktrace and Project are shared in the Comments section
- It looks like the Crash is being caused by a combination of dangling Animators in the Prefab and other dangling Component References
