[Bug] Account-Specific MODEL_CAPACITY_EXHAUSTED on ALL Models — Reinstall Did Not Fix

Hi Team,

I am a Google AI Pro subscriber and I am consistently getting the following error on my account across every model (Claude Opus 4.6, Claude Sonnet 4.6, Gemini 3.1 Pro High, Gemini 3.1 Pro Low, Gemini Flash) — every single time without exception.

Error: “Our servers are experiencing high traffic right now, please try again in a minute.”


What I have already tried:

  • Full uninstall and clean reinstall of Antigravity
  • Cleared all cache, session storage, and GPUCache manually
  • Tested on multiple models — all fail
  • Tested on a second Google AI Pro account on the same machine — works perfectly
  • Enabled AI Credit Overages toggle in Settings → Models
  • Model quota bars show nearly zero usage — this is NOT a quota exhaustion issue

This confirms the issue is isolated to this specific account on the backend, not my machine, network, or quota.

Request: Please investigate and reset the backend state for this account. I am a paying Pro subscriber and have not been able to use the service at all this month. Happy to provide any additional logs or information needed.
