Steps to reproduce:
1. Create a new Unity project
2. Open Build Profiles window
3. Switch to Web Platform
4. Go to Edit -> Project Settings -> Player -> Other Settings
5. Find and uncheck Auto Graphics API
6. Select WebGPU (Experimental) Graphics API
7. Go back to to Build Profiles window
8. Build the project

Actual results: Shader compiler and shader errors are thrown in the Console window after project is built
Expected results: No errors are thrown in the Console window after project is built

Reproducible with versions: 6000.4.0b9 (74e5d09f9bc7), 6000.4.0b10
Not reproducible with versions: 6000.3.10f1, 6000.5.0a7, 6000.4.0b8 (f3f87a02ba54) 

Tested on (OS): Ubuntu 24.04 (repro), macOS Silicon Tahoe 26.2 (M1) (no repro)

Notes:

•  Building on Web Platform might take ~15 minutes.
