How to reproduce:
1. Create a new Unity project with the Universal 3D template
2. In the Project window, select the "PC_Renderer" asset
3. In the Inspector, set "Rendering Path" to "Deferred"
4. Enable the "Tile-Only Mode" checkbox
5. Under "Post-processing", disable the "Enabled" checkbox
6. Enter Play Mode
7. Observe the Console

Expected results: No errors are thrown and Screen Space Ambient Occlusion is either applied or skipped with a single warning, as with "Rendering Path" set to "Forward"
Actual results: "Render Graph Execution error" and "InvalidOperationException: The On-Tile Validation layer has detected an issue: render pass 'Copy Depth' calls 'UseTexture' with resource '_CameraDepthAttachment'." errors are thrown continuously (~1000 per second)

Reproducible with: 6000.7.0a2, 6000.7.0b3
Not reproducible with: 6000.7.0a1

Reproducible on: macOS Tahoe 26 (M1), Ubuntu 24.04
Not reproducible on: No other environment tested

Note: In 6000.7.0a1 only warnings are spammed
