Hi Google Antigravity team,
I am experiencing a persistent login issue with Antigravity that seems to be tied to a specific Google account, while other accounts work fine.
Symptoms
On macOS, with the latest Antigravity version (updated on February 21, 2026), when I sign in, the OAuth flow completes successfully in the browser.
Antigravity then shows the error dialog:
“There was an unexpected issue setting up your account. Please try again later.”
The same error happens on another computer with a fresh Antigravity install.
If I sign in with a different Google account on the same machines and same Antigravity version, everything works normally: the account is set up, models load, and agents run without issues.
What I have already tried
Fully closing Antigravity and clearing local data on macOS:
~/Library/Application Support/Antigravity
~/.gemini/antigravity
~/Library/Caches/Antigravity
Reinstalling Antigravity from scratch.
Testing from another macOS machine with a clean installation.
Checking my Google Account security:
No security alerts.
No suspicious third‑party apps with broad access (I removed all non‑essential connections).
Logging in via browser works, and the OAuth callback is called, but Antigravity fails during the account setup step with the error above.
This looks like either:
a corrupted Antigravity account state for this specific Google account, or
an eligibility / Terms‑of‑Service flag that is not clearly surfaced to the user.
I would like to continue using Antigravity with this account if possible.
Request
Could you please check the backend status of my Google account for Antigravity and reset or unblock its Antigravity state, if it has been flagged or corrupted?
If my account is considered ineligible or disabled for Antigravity, please let me know explicitly (and whether there is any path to restore access).
I can provide timestamps, screenshots of the error dialog, and browser DevTools logs (network tab) showing the successful OAuth callback followed by the failure, if that helps.
Thank you in advance for your help.
