Steps to reproduce:
1. Open the “IN-68197_REPRO.zip” Project
2. In Project Settings > Graphics, assign the HDRP asset
3. Observe the Scene and Game views

Expected results: The Scene and Game views are rendering
Actual results: The Scene and Game views are not rendering

Reproducible with: 2021.3.36f1, 2022.3.26f1, 2023.2.19f1, 6000.0.b16

Reproducible on: Windows 11
Not reproducible on: No other environment tested

Workaround:
1. Increase the Shader Variant Limit to a higher value, for example, 128 (Project Settings > ShaderGraph, or Preferences > Shader Graph)
1.1. If it auto reverts to 64 open any shader graph file and try again
2. Reimport all assets (Right-click inside the Project window, and select “Reimport all”)

Notes:
- Reproducible in an empty project
- To reproduce: Install HDPR package, set Shader Variant Limit to 64, reimport all assets
- Reproduction happens if the Shader Variant Limit is set to anything lower than 96
