I am reporting a persistent login loop in the Antigravity desktop app on macOS. After successfully logging in via the browser and being redirected back, the app fails to authenticate and returns to the “Sign into Google” screen.
Specific Issue: This is happening on a Family Group member’s account which shares a Google AI Pro subscription. My primary account works fine, but this specific family member’s account cannot bypass the login screen despite having the Pro benefits active.
Steps already taken with no resolution:
-
Cleared macOS Keychain entries.
-
Revoked app access from Google account settings.
-
Switched default browsers (Chrome and Safari).
-
Cleared all app caches and deleted local configuration files.
-
Verified account age (18+) and region (Mexico).
-
No VPN is active.
