Webview Error Authenticating In Amazon Q

## Problem

AWS Authentication fails with stackblitz.com GitHub integration setup.

## Steps to reproduce the issue

1. Go to Amazon Q Extension: 'Choose a sign-in option' menu
2. Click on 'Personal account', then click "continue"
3. See error in the log.
Notably the "workspace deletion failed" warning confuses me, as I did not even trigger a workspace deletion request:

## Expected behavior

AWS Authentication, I assume.

## System details (run `AWS: About` and/or `Amazon Q: About`)

Amazon Q: About Output

- OS: Linux x64 5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/142.0.0.0 Safari/537.36
- Visual Studio Code extension host: 1.84.0
- Amazon Q: 1.106.0
- node: 20.19.1

Start from the Amazon Q Extension “Choose a sign-in option” menu and reproduce the Personal account flow in the StackBlitz GitHub integration. Investigate the logged dynamic-module fetch failure and confirm that AWS authentication succeeds without an unrelated workspace-deletion warning.
