Default Renderer is missing, make sure there is a Renderer assigned as the default

I got the following error.

Default Renderer is missing, make sure
there is a Renderer assigned as the
default on the current Universal RP
asset:UniversalRP-HighQuality
UnityEngine.GUIUtility:ProcessEvent(Int32,
IntPtr)

Where and how can I fix this problem?

Have you put 2D Renderer in Universal Render Pipeline Asset.
