Antigravity IDE stuck in "Further action is required" loop for Paid Subscription Account

Hello Antigravity Team,

I am writing to request urgent support regarding a persistent authentication issue with Antigravity IDE. My Google account is an active paid Google One subscriber, but I am completely blocked from logging in.

1. Problem Description

Whenever I attempt to sign in to the Antigravity desktop app, I am stuck in an infinite verification loop showing the following message:

“Further action is required to use Antigravity IDE. Please verify your account, then sign in again to continue.”

Please note that I have already completed phone number verification, adult identity verification, and Passkey setups on this Google account. I even have the confirmation screen showing identity verification is complete. However, Antigravity IDE continues to trigger an infinite loading/verification loop.

I contacted Google One Customer Support, and they confirmed that my account status, payment/subscription, identity, and age verification are all active and normal. They advised me to reach out directly to the Antigravity engineering team.

2. Workarounds Attempted (All Failed)

We have tried multiple troubleshooting steps to bypass or resolve this issue, none of which worked:

  1. main.js Core File Modification:
    • Located the application source file (main.js in resources/app) and manually edited the code.
    • Inserted BigInt.prototype.toJSON = function() { return this.toString(); }; at the very top line of main.js to prevent JSON serialization crash/freeze during login state parsing.
  2. Account Security & Verification:
    • Registered and verified Passkeys on both PC and mobile devices.
    • Cleared connected app permissions in Google Account Settings (myaccount.google.com/connections) and attempted a fresh re-authentication.
  3. Browser Isolation:
    • Attempted sign-in using clean Chrome browser profiles with cleared cache and cookies.
  4. Gemini CLI Session Force-Sync:
    • Installed gemini-cli via npm and attempted authentication.
    • Switched to Gemini API Key authentication (gemini-api-key), successfully authenticated the CLI, changed models to gemini-3.1-flash-lite, and submitted session sync prompts (I want to use Antigravity with this account.).
    • Even though the CLI acknowledged the Antigravity installation and synced successfully, the desktop app STILL prompts the same “Further action is required” loop upon launch.

3. Request

Since all local file modifications, troubleshooting steps, and CLI session syncs have failed, it appears my account is stuck in a backend flag on the Antigravity server.

Could you please review my account status and reset/unblock the verification flag on the backend?

(Note: Please reach out to me via DM or private message if you need my specific account email address for verification.)

Thank you for your assistance.

Hi @ept_jic

Could you please try these deep reset steps:

1. Clear Browser Connections by closing the IDE entirely. Open your default web browser, navigate to your Google Account Connections settings, find Antigravity, and select ‘Delete all connections’. Ensure you sign out of any secondary or Work accounts in that browser session so only your paid account is active.
2. Reset Onboarding by relaunching Antigravity, open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P) and run the command: Antigravity: Reset onboarding.
3. If the loop persists, completely close the app and manually delete your local configuration folder (%APPDATA%\Antigravity on Windows, or ~/.config/Antigravity/ on Mac/Linux)
4. Then relaunch the IDE, click ‘Sign In,’ and complete the login flow.

Hello Antigravity Support Team,

Thank you for the detailed response.

I have carefully executed all 4 deep reset steps as instructed:

  1. Completely closed the IDE, cleared ‘Antigravity’ from Google Account Connections, and signed out of all secondary/work accounts in the browser.
  2. Relaunched the app and ran ‘Antigravity: Reset onboarding’ from the Command Palette (Ctrl+Shift+P).
  3. Completely closed the app again and manually deleted the entire local configuration directory at %APPDATA%\Antigravity.
  4. Relaunched the IDE and attempted a fresh sign-in.

Unfortunately, the exact same verification loop persists:

“Further action is required to use Antigravity IDE. Please verify your account, then sign in again to continue.”

Since all client-side configurations, local cache, and connection tokens have been completely wiped and reset, this confirms the issue is located on the server/backend side regarding my account’s entitlement flag.

Could you please escalate this issue to the backend engineering team to manually reset/unblock the Antigravity entitlement flag for my account?

(Please let me know if you need me to provide my account email via a secure private message.)

Thank you for your continued support.

This looks like a bug in the early-access flag system. Antigravity may be applying some “account not fully verified” check that doesn’t correctly read the fact that your Google Account has already passed all verifications.

A backend engineer will need to inspect your account’s OAuth grants and the internal antigravity_entitled or verified flag, then either reset it or set it manually.

Once the flag is cleared, your next fresh sign-in (after one more Reset onboarding + config deletion) should go through.

My Pro account (m...@gmail.com) is stuck in the ‘Further action is required to use Antigravity’ loop. Browser completes with Auth Success, phone number and 2FA are fully verified, but the IDE will not unlock. Please check and reset the internal antigravity_entitled / verification flag on my account.
