    Suddenly I got this error on Unity:

    InvalidCastException: Specified cast is not valid.
    UnityEngine.UI.ScrollRect.get_viewRect () (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/ScrollRect.cs:454)
    UnityEngine.UI.ScrollRect.UpdateCachedData () (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/ScrollRect.cs:542)
    UnityEngine.UI.ScrollRect.Rebuild (UnityEngine.UI.CanvasUpdate executing) (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/ScrollRect.cs:516)
    UnityEngine.UI.CanvasUpdateRegistry.PerformUpdate () (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/CanvasUpdateRegistry.cs:182)
    UnityEngine.UI.ScrollRect:LateUpdate() (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/ScrollRect.cs:808)


    The GameObjects using ScrollRect appear as Missing Prefab (Dummy).

    Maybe because I'm changing from Unity Version 2020.3.13f1 to Unity Version 2020.3.15f2 using the same project?

    Which cache should I clear to make it work?

    Thanks!

    SOLVED!

    Deleting entire Project /Library folder and force to recreate again opening the editor solved the problem!
