Reproduction steps:
1. Create and open a project with the “Universal 3D“ template
2. Create a Shader Graph (Assets > Create > Shader Graph > Blank Shader Graph)
3. Open the created Shader Graph using the Shader Editor
4. In the Shader Editor window, create a “Simple Noise” (Context menu > Create Node)
5. Observe the preview of the noise in the created Node

Expected result: The noise is displayed in the preview
Actual result: The preview is all black

Reproducible with: 2021.3.45f1, 2022.3.51f1, 6000.0.24f1

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

Note: Setting an active target in the Graph Settings fixes the issue for nodes created afterwards, but for the nodes created before, you need to close and reopen the Shader Editor
