Unable to complete account setup - "unexpected issue setting up your account" (1 week, no resolution)

I have been unable to use Google Antigravity for over a week. After signing in with my personal Google account, the browser shows “You have successfully authenticated,” but the Antigravity app always displays: “There was an unexpected issue setting up your account. We apologize for the inconvenience. Please try again later.”

This error occurs at the account setup step during onboarding (step 6 of 7), after configuring editor settings. The issue persists even after the latest app update.

What I’ve tried (all failed):

  • Clean uninstall and reinstall (deleted ~/Library/Application Support/Antigravity, ~/Library/Caches/Antigravity, ~/Library/Preferences/antigravity, ~/.antigravity)

  • Revoked Antigravity access from Google Account permissions and re-authenticated

  • Flushed DNS cache (sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder)

  • Restarted the app and macOS multiple times

  • Updated Antigravity to the latest version

  • Submitted feedback via in-app “Having trouble? Let us know” form (Auth and Billing category, with server logs attached) on Feb 20, 2026 — no response after 6 days

I previously used this account with a third-party service that accessed Gemini via Antigravity’s API. I have since disconnected it and revoked access, but suspect server-side account state may be conflicting with the IDE setup process.

Environment:

  • OS: macOS (Apple Silicon)

  • Antigravity: Latest version

  • Account: Personal Google account (@gmail.com) with Google AI Pro subscription

  • Region: Japan

Could someone from the team please check my account’s server-side state and reset the account setup? Browser authentication succeeds every time, so the issue is clearly in the post-authentication provisioning step.

Thank you.
