Hi @Farooq,
Welcome to the Forum,
This issue sometimes occurs when the login request is flagged by OAuth security systems or if the application cache gets corrupted after becoming unresponsive.
You can try following workarounds to resolve the issue
-
Switch your network connection: Connect your device to a mobile hotspot or VPN temporarily, then attempt sign-in again.
-
Clear local cache & App Data:
macOS: Delete
~/.gemini/and~/Library/Application Support/Antigravity.
Windows: Delete%APPDATA%\AntigravityandC:\Users\<Username>\.gemini.
If you are still experiencing issues after trying these steps, please submit a report directly in the app via Feedback so our team can inspect the logs.
