Steps to reproduce:
1. Create a new Unity project using Universal 3D Sample Template
2. Open Build Profiles window and switch to Web Platform
3. Go to Edit -> Project Settings -> Player -> Other Settings
4. Find and uncheck Auto Graphics API
5. Select WebGPU (Experimental) in Graphics API
6. Clear errors in the Console if they are thrown
7. Go back to Build Profiles
8. In Scene List only enable “Scenes/Cockpit/CockpitScene”
9. Build and Run the project

Actual results: Project build fails, errors are thrown in the Console
Expected results: Project build doesn’t fail, no errors are thrown in the Console window
