Starting Virtual Player after Project upgrade throws Asset Database errors

Steps to reproduce:

1. Open the attached project
2. Open Multiplayer Play Mode window (Window -> Multiplayer -> Multiplayer Play Mode)
3. Start a Virtual Player
4. Observe the Virtual Player's Console window

Actual results: "Asset Database is set to Read Only, but it has found out-of-date assets. This should not happen!" and "Refresh completed but there are assets queued up for importing. Check for code that modifies assets which gets called after OnPostProcessAllAssets." errors are thrown in Virtual Player's Console

Expected results: No errors are thrown when Virtual Player is started

Reproducible with versions: 6000.3.0a2(1.6.1), 6000.3.0f1 (2.0.1), 6000.4.0a5(2.0.0), 6000.5.a2(2.0.1)

Not reproducible with versions: 6000.0.63f1 (1.6.1), 6000.2.14f1 (1.6.1), 6000.3.0a1(1.6.1)

Tested on (OS): macOS 26.1

Notes:

• The issue is most consistent when opening the project without the Library folder on a new Editor version.
• The issue is not tied to the MPPM package. Opening the project on 6000.3.0a1 will not reproduce the errors. Re-extracting the project and opening it with 6000.3.0a2 will reproduce the errors even though the MPPM package is 1.6.1 for both Editor patches.
