To reproduce:

1. Open Unity and create the new "2D URP" project
2. Install the Visual Effect Graph from the Package Manager
3. In the Project View Right-Click and select Create > Visual Effects > Visual Effect Graph
4. Leave the default "New VFX" name and confirm it with the Enter button
5. Open the "New VFX.vfx" Asset in Visual Effect Graph Window
6. Under Output Particle Quad node, select Shadergraph
7. Ensure the filter has the "Show Packages results" field enabled to see the default VFX Shadergraph

Expected result: In the "Select VFX Shader Graph" window you can see the "VFXSpriteLit" and the "VFXSpriteUnlit" Shader Graphs
Actual result: In the "Select VFX Shader Graph" window you can't see Shader Graphs just the "None" option

Notes:

• I’ve only managed to select those VFX Shader Graphs (the "VFXSpriteLit" and the "VFXSpriteUnlit") when I’ve copied them into the Project Asset directory

Reproducible in Unity 2022.2.0a16, 2022.2.0b6, and 2023.1.0a8
