I’d be interested in the same. Happened to me after upgrading from Unity 2017.x to 2019.1. Still looking for a way to get rid of this.

I had the same error. Seems to be linked to the fact that my object was hidden in the SceneVis tool. Error disappeared when I changes the visibility to show it again.

Thanks! Problem solved after changing the object to visible.

What is the SceneVis tool ? Is it some third-party tool?

This works for me:

private void Awake()
{
#if UNITY_EDITOR
    if (Application.isPlaying)
        UnityEditor.SceneVisibilityManager.instance.Show(gameObject, false);
#endif
    DontDestroyOnLoad(gameObject);
}

The console was being spammed with this error for me as well every time I’d enter Play Mode. Deleting the Library folder then reopening the project solved it. 2022.2.0b3, Windows 10.

Thanks for this thread, the scene visibility was indeed the issue, and the code above fixed it!

Can’t believe the scene visibility affects runtime logic
