The screen space reflection effect is not supported on OpenGL ES 3. It depends on a compute shader that is intentionally disabled because it caused issues with earlier OpenGL ES 3.1 drivers and in general the effect is not optimized for mobile.

Reproduction steps:

Open the user’s attached project (“KMainRepro“)
Go to File > Build Settings and change the platform to Android
Open the “/Assets/Scenes/SampleScene.unity” Scene
Observe the Console window

Expected result: Screen Space Reflections are working
Actual result: “Kernel 'KMain' not found” error is thrown

Reproducible with: 2021.2.0a20, 2021.3.14f1, 2022.1.23f1, 2022.2.0f1, 2023.1.0a21
Not reproducible with: 2020.3.42f1, 2021.2.0a19

Reproduced on: Windows 10 Enterprise 21H2

Notes:

When Screen Space Reflection on Post Processing V2 is enabled the following error appears
Reproduces on Built-in Render Pipeline
Uses OpenGLES3 as the Graphics API
