Ensure your Google account is verified with a phone number and meets the eligibility requirements for using Anti Gravity (not available for child accounts).

It's like a bug from Antigravity Manager.

When I manually login in Antigravity APP using Google OAuth, the same acount worked well.

So if you add an new account (never used AG before) in Antigravity Manager, this "Invalid project resource name projects/" error may occur. The solution is to finish an OAuth login process in Antigravity manually before using Antigravity Manager.
