Steps to reproduce:

1. Create a new Unity project
2. Open the "Create new Shader Graph Asset" window (Project window > right click > Create > Shader Graph > From Template...)
3. Select the "Canvas Meter" template, which should be displayed under the UGUI group, and click the "Create" button
4. Select a newly created shader graph in the "Project" window
5. In the shader graph window, find the "Graph Inspector" section
6. Click "+" and select "Custom Render Texture" in the "Active Targets" section 
7. Observe the result

Actual results: Console displays "Shader error in 'UGUI Canvas/Master': 'VertexColor' is not available in Custom Render Textures. at /(99)" error

Expected results: No errors in the Console view

Reproducible with versions: 6000.3.0b2, 6000.3.10f1, 6000.4.0b10, 6000.5.0a8

Can’t test with versions: 

• 6000.0.68f1 as the template window is not accessible in this build
• 6000.3.0b1 as "Canvas Meter"  template is not accessible in this build

Tested on (OS): macOS - Tahoe 26.2
