**Description:** I am experiencing a critical synchronization issue with Firebase Studio. While my application is currently deployed and running perfectly in production, the **Firebase Studio Preview** environment has completely reset to a blank/initial state.

**The Problem:**

1. **Missing Version History:** The buttons in the chat interface that allow rolling back to previous versions have completely disappeared.

2. **Preview Desync:** The Preview window no longer reflects the code that is currently live. It has reverted to a “start from scratch” state.

3. **UI/Cache Ruled Out:** I have already checked the browser console and tested in Incognito mode; it is not a local cache or rendering issue.

**Goal:** I need to recover the state of my project within the Studio so it matches what is currently published (Live). Since the “version buttons” in the chat are gone, is there a specific command or manual way to force the Studio Preview to re-import/sync from the current Hosting deployment?

**Technical Environment:**

- **App Status:** Published and working.

- **Platform:** Firebase Studio (AI Chat Interface).

- **Issue:** Total loss of versioning history/navigation buttons in the chat sidebar.

Any help on how to restore the Studio environment without affecting the live site would be greatly appreciated.
