## Steps to reproduce the issue

## Expected behavior

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

- OS:

Start by collecting the missing output from `AWS: About` and/or `Amazon Q: About`, along with the OS, Visual Studio Code, AWS Toolkit, and Amazon Q versions. Reproduce the unresponsive chat with a complete set of steps and use those details to identify the affected extension area; done means the failure is reproducible and its cause or next actionable scope is established.
