Steps to reproduce:

1. Create a new HDRP project
2. Import Water Samples from the HDRP package samples
3. Open the “Cave” scene
4. In the Hierarchy, select the “Water Sample Description” GameObject
5. In the Inspector, under the Custom Pass Triplanar Caustics section, click the script link

\\
Actual results: The error "Asset BindCaustics.cs could not be found" is thrown

Expected results: The link opens the corresponding BindCaustics.cs script if present, or the UI gracefully handles its absence with no error

\\
Reproducible with versions: 6000.0.48f1, 6000.1.0f1, 6000.2.0a9

Tested on (OS): Ubuntu 24
