Copilot in GitHub

Body

I am currently facing issues while using GitHub Copilot in Visual Studio Code.

Initially, I encountered the error “Language model unavailable.” After troubleshooting, I started getting a different error in Copilot Chat: “Access denied – You do not have permission to view this.”

I have already tried the following steps:

Signed out and signed back into both GitHub and Copilot
Reloaded and restarted Visual Studio Code
Cleared Copilot and Copilot Chat cache folders
Removed custom configurations related to MCP and GitLens
Disabled GitLens extension temporarily
Ensured that the Copilot extension and Copilot Chat extension are installed and enabled

Despite these efforts, the issue still persists.

Could you please help me resolve this issue? Also, kindly confirm if my account has proper access to GitHub Copilot Chat and whether there are any restrictions or configuration issues on my account.
