To reproduce:

# Open Unity and create the new "2D URP" project
# Install the Visual Effect Graph from the Package Manager
# In the Project View Right-Click and select Create > Visual Effects > Visual Effect Graph
# Leave the default "New VFX" name and confirm it with the Enter button
# Open the "New VFX.vfx" Asset in Visual Effect Graph Window
# Under Output Particle Quad node, select Shadergraph
# 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
