How to reproduce:
1. Open the user's attached "Difference Analyzer.zip" project
2. Go to Window -> Layouts -> Default
3. Enter Play Mode
4. Observe the Game view
5. Select the "Background" GameObject in the Hierarchy window
6. Observe the Inspector window
7. Press on the Scene Tab
8. Observe the Console log

Expected result: Textures are visible in the Game view and the Inspector window shows the Components normally (step 4, 6). When pressing on the Scene Tab no errors are thrown and the whole Scene is visible (step 8)
Actual result: The Game view and the Inspector window are black (step 4, 6). When pressing on the Scene Tab it also appears to be black and multiple errors are getting spammed in the Console log (step 8)

Reproducible with: 7.4.3 (2019.4.10f1), 9.0.0-preview.55 (2020.1.5f1), 10.0.0-preview.26 (2020.2.0b2)
Could not test with: 4.0.0-preview (2018.4.27f1) - RenderPipelineManager is not available

Notes:
- The issue is also reproducible with "Screen Space - Overlay" and "World Space" Render Modes
- If both the Scene view and Game view are visible, no errors will get spammed in the Console log
