Description

## Problem
When I install the amazon Q extension in my VS code IDE, It is not working as expected and the interface shows only the loading screen and never turn back to chat interface or login
## Expected behavior
After installation should work as expected and redirect either chat interface or the login

Research direction

Reproduce the failure on Ubuntu 24.04.3 with VS Code 1.104.1, then inspect Amazon Q Logs.log and the language-server startup command shown in the issue. Done means the Amazon Q server no longer repeatedly closes and reaches either the chat interface or login instead of stopping after five restart attempts.
