ArgumentException Thrown When Toggling Subscene Load State at Runtime

Steps to reproduce:

1. Create a new Unity project
2. Open the Package Manager
3. Install the *com.unity.vehicles * package
4. Select the Vehicles package and open the Samples tab
5. Import the Advanced Vehicle Sample
6. In the Project window, open the AdvancedVehicleScene
7. In the Hierarchy, select the AdvancedVehicleSubscene GameObject
8. In the Inspector, ensure Auto Load Scene is disabled
9. Enter Play Mode
10. Manually enable the Load Scene checkbox
11. Then disable it
12. Enable it again
13. Observe the Console

Actual results: The following exception is thrown in the Console:

ArgumentException: System.ArgumentException: The entity does not exist.System.String Unity.Entities.EntityComponentStore::AppendDestroyedEntityRecordError(Unity.Entities.Entity)
This Exception was thrown from a function compiled with Burst, which has limited exception support

Expected results: Toggling the subscene load state during runtime should not trigger an exception. The entity management system should handle state transitions without throwing errors.

Reproducible with versions: 0.1.0-exp.10 (6000.2.0b3)

Tested on (OS): Windows 11
