How to reproduce:
1. Create a new empty URP project
2. Import the attached “BrokenShader.shadergraph” file
3. Observe the Console Window

Expected result: No errors are shown in the Console
Actual result: an “undeclared identifier ‘LinearToSRGB'“ error is shown in the Console

Reproducible in: 2022.3.53f1, 6000.0.28f1, 6000.1.0a5
Could not test with: 2021.3.46f1 (Custom Render Texture target does not exist)

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

Note: Changing the “Color” variable’s Color Mode (under node settings) to “Default”, or removing the Custom Render Texture target (under Graph Settings) will remove the error
