Antigravity Login Bug — OAuth Succeeds in Browser but App Stays on Login Screen (Google AI Pro Account)

Hi,

I’m experiencing a persistent login issue with Google Antigravity that is isolated to one specific Google account.

Problem:
When I click “Sign in with Google” in Antigravity, it opens the browser and the authentication completes successfully — the browser shows the success/redirecting message. However, Antigravity never picks up the login. It stays on the “Sign in with Google” screen as if nothing happened. No error messages, no “Setting up your account” screen — just nothing.

Key details:

  • The affected account is a personal Gmail account (this account that im posting this post with) with a Google AI Pro subscription.
  • I have multiple other Google accounts and they ALL log in to Antigravity without any issues.
  • My region is Turkey (supported), my IP is in Turkey, and my phone number is Turkish — all matching.
  • The account is not and has never been suspended.
  • I am over 18, verified with a credit card.
  • Tested on two different computers — same result.
  • Tested with both Chrome and Edge as default browser — same result.
  • Other accounts work perfectly on the same machines and browsers.

This tells me the issue is account-level on Google’s backend, not client-side.

Expected behavior: After successful OAuth in the browser, Antigravity should proceed to account setup and open the IDE.

Actual behavior: Antigravity remains stuck on the login screen with no feedback.

I’ve seen several other posts here describing the same issue, particularly with Pro accounts. Would appreciate any help or acknowledgment that this is being looked into.

Thanks.

I experienced something similar. I’ve found that restarting Antigravity twice fixes it. Make sure Antigravity is fully stopped each time, no running processes.

Same problem here. Windows and Ubuntu with Google AI Pro. Have tried restarting, deleting AppData, re-install Antigravity but nothing works so far.

This issue still remains, effectively I cannot use antigravity.
