One Gmail account cannot sign in to Antigravity — browser succeeds but app stays logged out (requesting backend account reset)

Google Antigravity

Hi @Shivam_Singh2 and Google Antigravity team,

I am experiencing a persistent login issue with one specific Gmail account on Windows 11.

Problem Account:
OS: Windows 11

Symptoms:

  • Clicking “Sign in with Google” in the Antigravity app opens the browser normally.
  • Google authentication completes and the browser shows success.
  • However, the Antigravity app never transitions to a logged-in state — no error message is shown.
  • All other Gmail accounts on the same PC and network log in to Antigravity without any issues.
  • In Google Account security settings, the age/birthday, phone number, and country (South Korea) are all correct. Google Antigravity also appears under “Third-party apps & services” with permissions granted.

Steps Already Tried (without success):

  • Uninstalled and reinstalled the latest version of Antigravity
  • Fully deleted the %APPDATA%\Antigravity folder
  • Changed default browser and cleared all cookies/site data
  • Removed Google Antigravity from Google Account “Third-party apps & services” and re-authorized — issue persists

Request:
I found this resolved thread where a backend account provisioning/eligibility reset fixed the same issue:

Could the Google Antigravity team please check the following for .....@gmail.com on the server side:

  1. eligibility / provisioning flag status
  2. token / session state

And if possible, perform an account state reset for this account?

I am happy to provide any additional logs or information. Thank you very much.
