[HDRP] Error spam when assigning invalid custom material to a water component



If you assign an invalid custom material to a water component, the console will get sapmmed with errors similar to the following:
Trying to access pass -1, but material 'x' subshader (0) has only y valid passes.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&) {code}
If you assign None or a generated water material, you don't get the error. Looks like a regression in 2023.2 (package version 16).

*Steps to reproduce:*

1. Open the attached project

2. Open Assets/OutdoorsScene.unity

3. Select the Ocean gameobject

4. In the Water Surface component under Appearance, open the Custom Material Object picker

5. Select any of the default materials


*Expected Result:*

The water isn't rendered but no errors appear in the console.

*Actual Result:*

The console is spammed with errors until the material is removed


Issue appears in 2023.2 using package version 16.x

Issue does not appear in 2023.1, 2022.3


Project and video attached.
