URGENT: Paid Pro Account Locked Out in Antigravity - HTTP 400 "Invalid project resource name projects/"

Hi Antigravity team and community,

I am a paid subscriber (AI Pro) completely locked out of using Antigravity due to a persistent backend authentication/project mapping issue.

Whenever I try to use any AI features within the IDE, the request fails because the underlying GCP project ID is missing from the payload. A newly registered free account works perfectly on the exact same machine, which isolates this strictly to a backend data mapping issue with my paid account.

1. The Error Logs:

2. Crucial Account Context (The likely culprit): I originally registered my Google account using a third-party email (408008556@qq.com), and later bound my current Gmail (wei8quan2bin5@gmail.com) as the primary alias. It appears that during this alias merge/SSO transition, the internal OAuth token lost its association with the auto-generated Google Cloud Project ID for my paid account.

3. Troubleshooting steps already taken (None worked):

  • Completely cleared the local .antigravity cache and did a fresh re-onboarding.

  • Hard revoked the OAuth access via myaccount.google.com/connections and re-authenticated.

  • Injected ANTIGRAVITY_PROJECT_ID manually via OS environment variables.

  • Tried logging in using the old original email alias.

Could a Google engineer please look up my TraceID and manually restore or regenerate the Project ID mapping for my account? I am currently blocked from utilizing the Pro subscription I paid for.

Thanks in advance for your help!
