How to reproduce:
1. Create a new 3D URP Sample project and open the "TerminalScene" scene
2. Go to Window -> Analysis -> Rendering Debugger -> Frequently Used -> Rendering Debug
3. Open the "Map Overlays" dropdown
4. Select the "Additional Lights Cookie Atlas" or "STP" overlay
5. Observe the results

Expected results: Map overlay doesn't break anything
Actual results: "NullReferenceException" and "Render Graph Execution error" errors are constantly spammed and Scene/Game views are not rendered
