Amazon Q hanging after any message

My Amazon Q hangs after any message is sent. It gets stuck in the "thinking" stage. I've uninstalled and installed multiple times along with disabling and reenabling it.

Start by reproducing the Amazon Q hang in the VS Code extension after sending a message, using the issue's reported reinstall and disable/reenable steps as context. Trace the message flow until it remains in the "thinking" stage; done means messages complete normally or the failure is isolated and documented with reproduction details.
