Terrain Tools, missing material bug in URP

Question

Hi, I am trying to use Terrain Tools with the universal render pipeline (URP), but as soon as I've installed it, it throws me this error message:

MissingReferenceException: The object of type 'Material' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object. UnityEditor.TerrainTools.TerrainToolboxUtilities.RevertPreviewMaterial () (at Library/PackageCache/com.unity.terrain-tools@4.0.3/Editor/TerrainToolbox/TerrainToolboxUtilities.cs:1853) UnityEditor.TerrainTools.TerrainToolboxUtilities.OnPlayModeChanged (UnityEditor.PlayModeStateChange state) (at Library/PackageCache/com.unity.terrain-tools@4.0.3/Editor/TerrainToolbox/TerrainToolboxUtilities.cs:2082) UnityEditor.EditorApplication.Internal_PlayModeStateChanged (UnityEditor.PlayModeStateChange state) (at :0)

I've tried to resolve the problem, but nothing seems to have helped. Does anyone know what the problem is and how to fix it?

The error message pops up even if I don't have a terrain in my project but I can still run my scene and it plays normally.

This happens in the "New Release" and "Preview" versions of the Unity Technology Terrain Tools. Double click the error message to edit the code. It will bring you to the line with the error. Add an IF statement so that it doesn't run the line if it is null if (m_PreviewMaterial != null) { m_PreviewMaterial.DisableKeyword("_SPLATMAP_PREVIEW"); //line with error }
