Exiting Play Mode after a script change throws 28 NullReferenceExceptions from the template's RobotManager subscribers

Steps to reproduce:

1. Create a new project from the Industry Fundamentals template
2. Open Assets/Scenes/Warehouse.unity
3. Enter Play Mode
4. Open Assets/Warehouse/Scripts/Robots/Robot.cs in a code editor
5. Add an empty line and save the file
6. Return to the Unity Editor
7. Exit Play Mode
8. Observe the Console

Actual results: 28 errors and a warning are logged while scripts reload:

NullReferenceException: Object reference not set to an instance of an object
Unity.Templates.IndustryFundamentals.Robot.OnEnable () (at Assets/Warehouse/Scripts/Robots/Robot.cs:28)
AudioControls: RobotManager.Instance is null!

Expected results: The scripts reload without errors

Reproducible with versions: 1.0.4 (6000.6.6f1, 6000.7.0b4, 7000.0.0a8)

Can't test with versions: 6000.3.26f1 - the template's scripts do not compile (RobotManager.cs(42,23): error CS1501)

Tested on (OS): macOS 27.0
