Google Antigravity Error unexpected issue setting up your account. Please try again later

Dear Google Antigravity Support Team,

I am writing to request technical assistance regarding my Google Antigravity IDE installation on Windows 11.

Despite having an active paid subscription associated with this Gmail account, I am unable to initialize the IDE.

While the web-based authentication process completes successfully (showing the “You have successfully authenticated” message), the IDE immediately returns the following error:

“There was an unexpected issue setting up your account. Please try again later.”

Environment Details:

Account Type: Personal Gmail (Paid Package)

Operating System: Windows 11

IDE Version: v3.0-COMPLETE (Enterprise Pro)

I have attached screenshots showing both the successful browser authentication and the subsequent error message within the IDE terminal. I have already attempted to restart the application and re-authenticate multiple times without success.

Could you please verify if there are any known service outages or if there is a specific configuration issue with my account provisioning?

Thank you for your time and I look forward to your quick response so I can get back to my development project.

Best regards,

Tahir
