Unified Ray Tracing Shader fails to compile (FXC crash) when debug symbols are enabled

How to reproduce:

1. Open the attached "IN-148316" project
2. In the Project tab in Assets, open the “NewUnifiedRayTracingShader.urtshader” in code editor
3. In the code editor, add “#pragma enable_debug_symbols” in the beginning and save the file
4. Observe results in the Console

Actual result: The errors during Shader compilation process in the Console of Unity Editor
Expected result: Shader compilation without errors

Reproducible with: 6000.6.0a1 (7dc703ab9bd8), 6000.6.0b5, 6000.7.0a3
Not Reproducible with: 6000.3.0a1, 6000.3.20f1, 6000.5.0a7, 6000.5.5f1
Could not test with: 6000.0.1f1, 6000.0.80f1 (Absence of “Unified Ray Tracing Shader”)

Reproducible on: Windows 11 Enterprise (25H2)
Not reproducible on: No other environments tested

Notes:

• Error thrown: “Shader compiler: Compile NewUnifiedRayTracingShader - MainRayGenShader: Lost connection with shader compiler process. Suspected crash in FXC.”
• Error thrown: “Shader error in 'NewUnifiedRayTracingShader': Compiling MainRayGenShader: Lost connection with shader compiler process. Suspected crash in FXC.”
