Builder Central (Beta) shows "Failed to fetch" on the welcome screen in my Agentforce Developer Edition org.
Console: CORS preflight to
https://api.salesforce.com/platform/dx-workspaces-proxy/v1/api/workspaces-proxy/<workspaceId>/project-service/v1/projects
is blocked. The OPTIONS response is HTTP 204 with no Access-Control-Allow-Origin header.
Reproducible with curl from outside the browser for any Origin, so it is not a client-side issue.
"Connect an org" logs in successfully but never returns to the app.
