"Kernel 'KMain' not found" errors appear when using the "Screen Space Reflections" Post-Processing effect in a specific WebGL project
How to reproduce:
1. Open the attached “IN-99437” project
2. Open the “3D_Test” Scene
3. In the Hierarchy window select the “Main Camera” (3D-SpatialAgent → Scene → 3D-Cursor → Main Camera) GameObject
4. In the Inspector window “Post-Process Volume” component make sure the “Screen Space Reflections” option is enabled
5. Observe the Console window
Expected result: No errors appear
Actual result: 2 “Kernel ‘KMain’ not found” errors appear

Resolution Note:
The ScreenSpaceReflection postprocess effect in that package uses a compute shader to do the blur pass, and WebGL does not support compute shaders, making that effect incompatible with WebGL.
