500 after separating Gmail from Workspace

Hi everyone. :man_raising_hand:t2:

Iā€™m getting a persistent HTTP 500 Internal Server Error in Antigravity after separating my personal Gmail account from my Workspace account.

Before this account separation, Antigravity was working. After the separation, my personal Gmail account started failing. Another Google account still works fine on the same Mac, same browser, and same network, so this does not look like a local/browser/network issue.

Creating a new chat/thread does not help either.

Here is the full error output:

Trajectory ID: 1a64ee5c-8986-4642-b15b-e975fc887
Error: HTTP 500 Internal Server Error
Sherlog: 
TraceID: 0x12f71f385c1fab72
Headers: {"Alt-Svc":["h3=\":443\"; ma=2592000,h3-29=\":443\"; ma=2592000"],"Content-Length":["109"],"Content-Type":["text/event-stream"],"Date":["Thu, 21 May 2026 04:32:32 GMT"],"Server":["ESF"],"Server-Timing":["gfet4t7; dur=311"],"Vary":["Origin","X-Origin","Referer"],"X-Cloudaicompanion-Trace-Id":["12f71f385c1fab72"],"X-Content-Type-Options":["nosniff"],"X-Frame-Options":["SAMEORIGIN"],"X-Xss-Protection":["0"]}

{
  "error": {
    "code": 500,
    "message": "Internal error encountered.",
    "status": "INTERNAL"
  }
}

The request fails very quickly, around 311 ms, and the response has Content-Type: text/event-stream, but the stream never starts.

Could someone from the Antigravity team check the backend logs for this TraceID / Trajectory ID?

This looks like an account-specific backend issue after the Gmail / Workspace separation, possibly related to identity mapping, account state, entitlement/quota, or model routing.

Thanks!
