Sampling a texture using an HLSL file throws shader errors and the code does not compile

Steps to reproduce:

1. Open the attached package
2. Open the New VFX.vfx
3. Open TexCodeEditor and TexShaderFile and notice that the code is identical
4. Plug TexShaderFile into Set Color block, then check the Scene view and console

Actual results: Code does not compile when it comes from shader file

Expected results: Code does compile when it comes from shader file

Reproducible with versions: 6000.0.47f1, 6000.0.60f1, 6000.2.8f1, 6000.4.0a3

Tested on (OS): macOS

Notes:{}

Shader errors:

• Shader error in '': redefinition of 'VFXSampler2D' at kernel CSMain at Assets/Tex.hlsl(1) (on metal)
• .compute: Kernel at index (0) is invalid

 

I bumped into crash several times when editing values (inconsistent):

• VisualEffectAssetUtility::SetValueSheet(PPtr<VisualEffectAsset> const&, VFXExpressionValuesSheetInternal const&, ScriptingExceptionPtr*) + 163
  VisualEffectAssetUtility_CUSTOM_SetValueSheet(void*, VFXExpressionValuesSheetInternal__ const&) + 139
