Cannot login – "Failed to exchange authorization code for token" after switching to new Mac (M1)

Google Antigravity
1

Hi Antigravity team,

I’m completely locked out of Antigravity after switching to a new MacBook (M1, Apple Silicon). The Google OAuth flow completes successfully and redirects back to the app, but the client stays stuck on the “Sign into Google” screen and never proceeds.

Error message: “There was an unexpected issue setting up your account. Failed to exchange authorization code for token.”

Environment:

  • OS: macOS, Apple Silicon (M1)

  • App: Antigravity (Apple Silicon version, latest)

  • Browser: Chrome (personal Gmail account)

What I’ve already tried:

  • Revoked Antigravity access in Google account third-party permissions and re-authorized

  • Tried multiple browsers

  • Cleared browser cookies for google.com and antigravity.google

  • Connected via US VPN during the entire login flow

  • Waited over 24 hours and retried multiple times

  • Fully quit and restarted the client each time

The OAuth redirect back to the client succeeds (no browser error), but the app never registers the login. This issue has persisted for over a day. Previously I used Antigravity on a different computer without any issues.

Please help – I’ve exhausted all client-side troubleshooting options.

Thank you!
