Virtual Player Clone Fails to Connect to Unity Package Manager in Multiplayer Play Mode

Steps to reproduce:

1. Create a new project using the MR Tabletop Template
2. Install the Multiplayer Play Mode package via the Package Manager
3.  Open the Multiplayer Play Mode Window (Window > Multiplayer > Multiplayer Play Mode)
4. Create a Virtual Player (e.g Player 2)
5. Check the Console output of the newly launched clone instance

Actual results: The following error appears in the clone’s console: "Failed to get package versions: Cannot connect to Unity Package Manager local server"
"Error retrieving package information from Package Manager: Cannot connect to Unity Package Manager local server.
UnityEditor.EditorApplication:Internal_CallUpdateFunctions () (at /home/bokken/build/output/unity/unity/Editor/Mono/EditorApplication.cs:384)"

Expected results: No errors or warnings should appear in the clone’s console. The Unity Package Manager should function correctly across all instances.

Reproducible with versions: 1.4.0, 1.4.0 (6000.1.b13)

Tested on (OS): Ubuntu 22
