Constant warning of 'null texture passed to GUI.DrawTexture'

When I opened my project, it gives constant warning in the console every frame. It continues no matter if it enters or gets out of play mode.
null texture passed to GUI.DrawTexture
UnityEngine.GUI:DrawTexture (UnityEngine.Rect,UnityEngine.Texture)
Bolt.Editor.Windows.BoltProjectWindow:OverlayIcon (string,int)
Bolt.Editor.Windows.BoltProjectWindow:DisplayAssetList (System.Collections.Generic.IEnumerable`1<Bolt.Compiler.AssetDefinition>)
Bolt.Editor.Windows.BoltProjectWindow:OnGUI ()
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

  • It disappears if I open another scene. And won't appear if open the original scene again.
