To install AI Assistant package

Click on the AI button in the menu bar (if it's not visible, right click, then Services/AI)

If the latest version is not compatible with Unity 6000.5, download this tarball

[https://drive.google.com/file/d/1OHg2GdbuEsIgQxPUpTJwgDGp7km_GLB-/view?usp=drive_link]

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

Note: To see the errors again, close and reopen the Unity project

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
