Virtual Player crashes when started from Multiplayer Play Mode after starting Host in a Netcode for Entities project

Steps to reproduce:

1. Create a new 3D URP project
2. Go to Window > Multiplayer > Multiplayer Center
3. Set "Genre of your Game" to Adventure and "Number of Players..." to 2
4. Change the "Netcode Solution" dropdown to "Netcode for Entities"
5. Click Install Packages
6. Once installed, click "Create and open scene with netcode setup"
7. Enter Play mode and click "Start Host"
8. Open Window > Multiplayer > Multiplayer Play mode and start "Player 2"
9. If it doesn't crash after loading, click the "Pause" button in the Editor toolbar to unpause
10. Observe the Player 2

Alternative reproduction steps for 6.6 (due to change of Multiplayer Center):{}

1. Open the attached project
2. Open the "Connection UI" scene
3. Enter Play mode and click "Start Host"
4. Open Window > Multiplayer > Multiplayer Play mode and start "Player 2"
5. If it doesn't crash after loading, click the "Pause" button in the Editor toolbar to unpause
6. Observe the Player 2

Actual results: "Player 2 unexpectedly stopped" popup appears and Player 2 crashes, Bug Reporter opens

Expected results: Player 2 instance opens and does not crash

Reproducible with versions: 6000.5.0a8, 6000.5.0b9, 6000.6.0a5

Not reproducible with versions: 6000.3.16f1, 6000.4.8f1 (produces errors after 8th step, but the Player 2 does not crash)

Can’t test with versions: 6000.5.0a1 - 6000.5.0a7 (compiler errors when installing packages prevent from entering Play mode

Tested on (OS): macOS 26.5

Notes:

• Does not reproduce if Netcode for GameObject is selected in the 4th step
• Does not reproduce if Player 2 instance is started before clicking "Start Host"
