Steps to reproduce:
1. Create a new Unity project using Universal 3D Sample Template
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. Add WebGPU (Experimental) in Graphics API
7. Observe the errors in the Console window

Actual results: Errors are thrown in the Console window after adding WebGPU Graphics API
Expected results: No errors are thrown in the Console window after adding WebGPU Graphics API

Reproducible with versions: 6000.3.10f1, 6000.4.0b10, 6000.5.0a7
Can’t test with versions: 6000.0.67f1 (WebGPU not available)

Tested on (OS): Ubuntu 24.04 (issue is reproducible), macOS Silicon Tahoe 26.2 (M1) (issue is not reproducible)
