Steps to reproduce:

1. Create a new HDRP 3D Template

2. Open Render Graph Viewer

3. Observe Scene or Game view (Depending on Render Graph Viever's target camera)

Actual results: Scene view is flickering in Gray and Gizmos are missing. Game view is flickering in black. Render Graph Viewer's results cannot be captured. Multiple errors are thrown as well

Expected results: Render results for Scene or Main Camera are unaffected by Render Graph Viewer

Reproducible with versions: 6000.0.0f1

Not reproducible with versions: 2021.3.37f1, 2022.3.22f1, 2023.2.20f1, 6000.0.0b16

Tested on (OS): macOS 14.4.1 (Intel), Windows 11
