Reproduction steps:

1. Open the project “ReproRealtimeReflections”
2. Build and run the project
3. Observe the sphere in the middle
4. Come back to the project
5. Go into Project Settings > Graphics > Always Included Shaders and set Size to 0 (so no shaders are "always included")
6. Build and run the project
7. Observe the sphere in the middle

Expected result: The sphere is still reflective or a ‘shader missing’ error is thrown
Actual result: The sphere is no longer reflective
