Hi @avora_host, welcome to the forum!

Could you please follow below steps:

If you are using a Personal Account (@gmail.com):

  1. Click your account avatar in the top-right corner of Antigravity (or run agy auth logout in your terminal) and log out.
  2. When the sign-in browser window opens, make sure you choose Personal Account (not Business account or Continue with Google Cloud).
  3. If the error persists, close the app and clear your local session cache:
    • Windows Delete %AppData%\Antigravity and %USERPROFILE%\.gemini
    • macOS/Linux: Delete ~/.gemini and ~/Library/Application Support/Antigravity
    • Then reopen Antigravity and sign in again.
  4. Ensure you are running the latest version, as older builds occasionally forced enterprise validation checks.

dont work( The error persists; I have four new Google accounts (new in the sense of being for Anti-Gravity—the accounts themselves are actually 3+ years old), and none of them work. I’ve tried reinstalling and everything else—nothing helps.

Same here, the problem has been going on for several days now.

Hi Antigravity Engineering Team, I am completely locked out of the Antigravity IDE due to a persistent Error #3501 (“You do not have a valid license of this product”). Account Type: Personal Account (St***********@gmail.com) Plan: Free Starter Quota Tier Troubleshooting Steps Already Completed: 1. Fully uninstalled and reinstalled the application. 2. Manually deleted the hidden %APPDATA%\Antigravity and ~/.gemini configuration folders. 3. Attempted to log in via clean Incognito browsing sessions. 4. Tested the login loop with 2 completely different alternative personal emails, but Error #3501 remains on all of them. Since this issue is persisting across clean accounts on my machine, it appears my client app configuration is forcefully routing to the enterprise cloud validation endpoint rather than checking my personal consumer entitlement. Could a backend administrator please verify my account routing flags and manually reset the license/entitlement settings for my profile? Thank you!
