Reproduction steps:
1. Open the attached “IN-102605_MissingRenderingLayers - Repro.zip“ project
2. Open the “SampleScene”
3. Open the Frame Debugger window (Window > Analysis > Frame Debugger)
4. Press the “Enable” button
5. Observe the custom pass “(RP 4:2) TestPass”

Expected result: Rendering layer data is available for a custom pass (all three spheres are on different layers and are shown in different colours in the rendering layers texture)
Actual result: Rendering layer texture “_GBuffer5” is bound but the texture is completely black/empty

Reproducible with: 6000.0.54f1, 6000.1.14f1, 6000.2.0b11, 6000.3.0a3
Could not test with: 2023.1.0a1 (feature not available)

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- Assets/ShowRenderingLayersFeature.cs contains the code for the custom pass
- Moving the custom render pass event from RenderPassEvent.BeforeRenderingTransparents to RenderPassEvent.AfterRenderingGbuffer did not resolve the issue
- Reproducible in the Player (the black UniversalResourceData.renderingLayersTexture covers the entire screen)
- Reproducible in a new project (when using the same script for the custom URP ScriptableRendererFeature)
