HD (Unknown) “Cannot find the code for this Target, a package may be missing.” warning is thrown when creating a new ShaderGraph Decal from template for a Decal Projector Material

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Decal Projector (GameObject > Rendering > URP Decal Projector)
3. Select the newly created Decal Projector in the Hierarchy window
4. Click on the "New" dropdown next to the Material property in the Inspector window
5. Select "ShaderGraph Decal from template"
6. Select the "Decal Simple" Shader Graph and click the "Create" button
7. Press Enter to finish naming the new Shader Graph
8. Open the newly created Shader Graph
9. Observe the Graph Inspector

Actual results: HD (Unknown) “Cannot find the code for this Target, a package may be missing.” warning is thrown in the Graph Inspector

Expected results: No warnings or errors in the Graph Inspector

Reproducible with versions: 6000.5.0b4, 6000.6.0a3

Can’t test with versions: 2023.1.0a3, 6000.0.73f1, 6000.3.13f1, 6000.4.3f1 (due to no ShaderGraph Decal from template option in the Decal Projector)

Tested on (OS): MacOS Silicon Tahoe 26.3
