[Bug] Exhausting Claude/GPT quota completely blocks Gemini models (HTTP 429) and breaks Workspaces UI (__store is null)

Description:

I encountered a bug where exhausting the quota for one set of models (Claude via Claude Code Extension) completely locks the account, preventing the use of Gemini models even when they have full quota available. Furthermore, this account-level lock breaks the Workspaces UI.

Steps to Reproduce:

  1. Use Claude models intensively via Antigravity until the quota is completely exhausted (Quota bars empty, :warning: warning icon appears).

  2. Switch the active model to Gemini 3.1 Pro or Gemini 3 Flash (which still show full quota bars).

  3. Send a prompt.

  4. Go to the Settings > Workspaces tab.

Expected Behavior:

  • Gemini models should process the prompt normally since they have their own independent quota available.

  • The Workspaces tab should load my local workspaces without issues.

Actual Behavior:

  • Any prompt sent to Gemini fails immediately with an HTTP 429 Resource Exhausted error.

  • Clicking on the “Workspaces” tab in settings throws a UI crash: TypeError: Cannot read properties of null (reading '__store').

Troubleshooting done (Isolating the issue):

  • I cleared app Cache, Local Storage, Session Storage, and IndexedDB on both Windows and Mac.

  • I logged out and re-authenticated.

  • The key finding: Logging into a different Google account on the exact same machine/network works perfectly. The issue is strictly tied to my main account state after depleting the Claude quota. It seems the backend marks the entire account as RESOURCE_EXHAUSTED, overriding the available Gemini quota.

Error Logs:

Agent execution terminated due to error. (HTTP 429)
