"Shader error in 'Shader Graphs/Master': invalid subscript 'texCoord6' at /(243) (on d3d11)" error thrown when UV2-UV7 is connected to Base Color In Fullscreen Shader Graph

Steps to reproduce:

1. Create a new project using Universal 3D template
2. In Project Window, right-click > Create > Shader Graph > URP > Fullscreen Shader Graph
3. In the Shader Graph window, right-click > Create Node > UV
4. Connect the UV node to Base Color
5. In the UV node, change the Channel to anything from UV2 to UV7
6. Save and observe the Console

Actual results: "Shader error in 'Shader Graphs/Master': invalid subscript 'texCoord2' at /(243) (on d3d11)" and "[Worker0] Shader error in 'Shader Graphs/New Shader Graph'" errors

Expected results: No errors 

Reproducible with versions: 6000.0.71f1, 6000.3.11f1, 6000.4.0f1, 6000.5.0a9

Tested on (OS): Windows 11

Notes:

• The error is also thrown even after the created Shader Graph is deleted and a new one with no nodes is created
• Does not repro with UV0 and UV1
