"failed to make code assist backend request"

I have a subscription to the AI Pro plan, which all works fine except that I can’t run Antigravity since the version 2 upgrade (version 1 worked nicely). I’ve tried installing both the GUI and CLI versions on my regular Windows 11 machine and also a freshly installed Fedora laptop that’s never been logged in before. I just get “failed to make code assist backend request” when I log in. I’m based in New Zealand but Antigravity is supposed to be available here.

Additionally, there’s no way to provide feedback or ask for support from within the app, as the Submit button never lights up.

What’s the next course of action? I’ve already tried clearing out every mention of Antigravity from my machine, and also removing the app registration from my Google account so it has to fully reauthenticate. I don’t see any sort of errors or warnings in my account.

Thanks,
Julian.

Same issue, haven’t had a response in about two weeks

Same here, using Fedora too
