[DX12] Crash on D3D12RenderSubPassInfo::Begin when changing property value on custom Render Pass Feature

-

How to reproduce:
1. Open the attached “IN-101727” project
2. In the Project tab, “Settings” folder, select “PC_Renderer” asset
3. In the Inspector, expand the “Test” Renderer Feature and “Settings” submenu
4. Make sure “Use Async Compute” property is toggled on
5. Change the “Debug Probe Volume Mode” property to “Irradiance” or “Distance”
6. Observe the crash

Reproducible with: 6000.1.0b8, 6000.1.4f1, 6000.2.0b1
Couldn’t test with: 2022.3.62f1 (Missing namespace errors), 6000.0.49f1, 6000.1.0b7 (KeyNotFoundException and Render Graph Execution errors)

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

Notes:
- Does not reproduce when using DX11 or Vulkan Graphics APIs
- Does not reproduce when the “Use Async Compute” property is toggled off, or changing the “Debug Probe Volume Mode” to “Heightmap”

  1. Resolution Note (fix version 6000.3.0a2):

    Fixed by preventing WaitOnGPUFence and CreateGPUFence from crashing when used in middle of a render pass
