Antigravity – HTTP 400 “Invalid project resource name projects/” (Trajectory ID 97fc3458-1231-4b29-ae6a-....)

Hi,
I’m a Google AI Pro subscriber and I’m unable to use Antigravity agents with my main account even though it works with another Google account on the same machine/network.
Every agent request fails with:
HTTP 400 Bad Request
message: “Invalid project resource name projects/”
status: “INVALID_ARGUMENT”
Error details from the latest failure:

Trajectory ID: 97fc3458-1231-4b29-ae6a-cc…

TraceID: 0xcb18de8c142…

From what I can see, the project resource name is coming through as empty (projects/ with no project ID), so this looks like an account provisioning issue rather than a local configuration problem (similar to what other users have reported).
Things I have already tried (none of these worked):

Signing out and signing back into Antigravity

Deleting the local Antigravity config folder and reinstalling the IDE

Running gcloud auth login and gcloud auth application-default login

Running gcloud config set project and setting the GOOGLE_CLOUD_PROJECT env var

Testing from the same machine with a different Google account (that account works fine)

I also used the in‑app “Provide Feedback” form in Antigravity and successfully submitted a Bug Report with logs attached for this issue from this account.
Everything points to my account not being correctly associated with a valid project ID on the backend for Antigravity (the request is sent as projects/ instead of projects/).
Could a moderator or engineer please check this Trajectory ID / TraceID and re‑provision or bind my account to a valid project so that Antigravity agents can work again?
Thank you.

I have been experiencing this problem for nearly a month now. I have also submitted feedback through various channels to the authorities, but there has been no response at all.
