How to reproduce:
1. Open the attached project “ShaderStateBug”
2. Open the “SampleScene” scene
3. In the Packages/com.unity.render-pipelines.core/ShaderLibrary/Common.hlsl comment or uncomment the line “#pragma shader_feature REFLECTION_TYPE1 _MAIN_LIGHT_SHADOWS INSTANCING”
4. Click on the Editor to trigger the recompilation and during “Compile Compute variants” add the line “error” in the Common.hlsl
5. Trigger the recompilation again and delete the “error” line during “Compile Compute variants”
6. Enter the Play Mode

Expected result: There are no errors in the Console and the shaders work correctly
Actual result: The errors are still in the Console preventing shaders from rendering at all

Reproducible with: 2021.3.24f1, 2022.2.16f1, 2023.1.0b4, 2023.2.0a12
Couldn’t test with: 2020.3.48f1 (Compilation errors)

Reproducible on: Windows 11 Pro

Note: Restarting the Editor doesn’t clear the errors

Full error:
Exception: Compute Shader compilation error on platform D3D in file DebugLightVolumes.compute:24: undeclared identifier 'DEBUG_LIGHT_VOLUME_TILE_SIZE' at kernel LightVolumeColors
HDRP will not run until the error is fixed.
