# The provided script is designed to be useful for identifying broken references caused by the [SerializeReference] attribute in Unity. In Unity, when creating a prefab for a script in a scene, old values may persist, potentially disrupting the SerializeReference mechanism and leading to errors during scene opening or building. The script helps locate and identify broken .asset (YAML) references in the Unity project.
