Steps to reproduce:

1. Create a Unity project
2. Click the "AI" button
3. Click "Agree and install Unity AI"
4. Wait until the installation is complete
5. Observe the result in the "Console" view

Actual results: User gets these errors: "Lifecycle ERROR : could not enter scope 'CodeInitialized' due to required outer scope 'CodeLoaded' is not active." and "NullReferenceException: Object reference not set to an instance of an object"

Expected results: No errors in the Console view

Reproducible with versions: 1.7.0-pre.1(6000.5.0a7)

Not reproducible with versions: -

Tested on (OS): macOS - Tahoe 26.3
