How to reproduce:
1. Open the attached "PerceptionHDRP" project
2. Open the "SampleScene" Scene found in the Assets->Scenes folder
3. Open the Build Settings (File->Build Settings...)
4. In the Build Settings window make sure that the "SampleScene" is added to Scenes In Build and the Development Build is enabled
5. Build And Run
6. If the "Debug" window opens press "Ok"
7. After the Build launches close it

Expected results: No errors are thrown in the Development console
Actual results: "InvalidOperationException" errors are thrown in the Development console just before the Build closes

Reproducible with: 2019.3.1f1, 2019.4.8f1
Could not test with: 2018.4.26f1, 2019.3.0f6, 2020.1.0a1, 2020.1.3f1, 2020.2.0a20 because of the CS0115 and CS0246 errors

Notes:
- The errors are not thrown (and are not in the Player.log) only when the project you Build and Run the project, doesn't happen if you build and run the .exe afterwards
- The issue has been tested and reproduced on Windows
