Full error: [Worker0] MissingComponentException: There is no 'CanvasRenderer' attached to the "healthMask" game object, but a script is trying to access it.
You probably need to add a CanvasRenderer to the game object "healthMask". Or your script needs to check if the component is attached before using it.
UnityEngine.UI.Mask.OnDisable () (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/Mask.cs:99)
UnityEditor.AssetPreviewUpdater:CreatePreviewForAsset(Object, Object[], String)

Note: “CanvasRenderer” is attached to a “healthMask” GameObject
