ShaderVariantCollection cannot be created the first time if a shader has a fallback shader
How to reproduce:
1. Open the attached project named "Case_12361684"
2. Right-click in the project view -> Create -> CUSTOM_NAME (Edits below)
3. Observe the error in the console window
4. Repeat Step 2
5. Observe that the Shader Variant Collection was created this time
Expected result: Shader Variant Collection is created on the first time
Actual result: It takes two tries to create a Shader Variant Collection
Reproducible with: 2019.4.4f1(7.3.1, 7.4.1), 2020.1.0b15(8.1.0, 9.0.0-preview.35), 2020.2.0a18(10.0.0-preview.11)
Could not test with: 2018.4.25f1(URP was not yet available and the project would not downgrade due to custom packages)
Notes:
1. The issue re-occurs every time the project is launched

Latest issues
- After converting a Built-in project to URP render texture related errors are spammed that can lead to Game view being rendered on top of Scene view
- UI Builder slider value lags and stutters when sliding/modifying certain property values
- "Reset UI Builder Layout" functionality inconsistently changes Canva Size when "Match Game View" is enabled/disabled
- Texture Import Warnings are obscured by other Terrain Layer options in the Inspector
- Burst Inspector middle divider is jittering when resized with the Burst Inspector window docked
Resolution Note:
The user side scripts gather shader variants right after loading SRP assets, which resets the pipeline.
Restoring the asset and making the main camera render things once forces the shaders to reset their state. Shader data can be safely analysed after doing this.
