Failed to launch Amazon Q language server: Unable to find a compatible version of the Language Server
if I revert my amazon q to 1.60.0, everything works well. However with the latest version, this error I get. However code suggestions works fine. But not the chat. Chat window just keep loading indefinitely.

- OS:Windows 11
- Visual Studio Code version:1.100.3
- AWS Toolkit version:3.64.0

Research direction
No repository files, tests, or entry points are named. Start by reproducing the failure on Windows 11 with VS Code 1.100.3, AWS Toolkit 3.64.0, and Amazon Q 1.71.0, comparing it with Amazon Q 1.60.0 and reviewing the supplied logs. Done means the language server launches and the chat window no longer loads indefinitely.
