Troubleshooting Language Model Unavailable Error In VS Code Chat Extension
Problem Description
I encountered an issue where the language model became unavailable in the chat interface. This occurred after attempting to send a question. The system displayed a "Language model unavailable" message, and the models list disappeared from below the chat input. Even after deleting and re-adding the extension, the chat did not reset, and the problem persisted.
