Amazon Q VSCode Extension Builder ID Authentication Failure

Please help me authenticate to Amazon Q.

Trying to sign-in to Amazon Q using my Builder ID, vscode throws a "Failed to set up", and webview error. There is no browser launch (behaves the same for Chrome and Safari).

Logs show a connection refused error from localhost /client/register. Similar behavior when trying to authenticate CodeCatalyst with my Builder Id.

The same Builder Id works perfectly on a Windows 10 machine running the same version of VSCode, and same extension versions.

Already tried:

• Emptied all VSCode Cache related folders
• Removed ~/.aws/sso directory
• Deleted all active sessions from my Builder Id Security section
• Removed and reinstalled Q & Toolkit extensions

MacOS: Sonoma 14.5 VSCode: 1.91.1 Amazon Q Extension: 1.18.0 2024-07-29
