Steps to reproduce:

1. Create new Unity Project
2. Make sure Shader Graph package is imported to the project
3. In Package Manager select Samples 
4. Import UGUI Shaders Sample
5. Open "UISampleScene" (Assets > Samples > Shader Graph > 17.0.4 > UGUI Shaders > Scenes
6. Enter the Play mode and observe the Console

Actual results: "InvalidOperationException" errors are spammed in the Console

Expected results: No errors, UGUI Sample should be working without any issues

Reproducible with versions: 6000.0.47f1, 6000.1.0b15, 6000.2.0a9

Can’t test with versions: 2022.3.61f1 (UGUI Shader sample not available)

Tested on (OS): Windows 11 (22H2)

Notes:

• 6000.0.47f1 uses Active Input Handling > Both, but after switching to New Input System in Player settings, errors are spammed in the Console. On higher U6 versions, you need to switch to old Input System for Sample to work, because it is using New Input System.
