You're hitting a JSON parsing error that usually means Copilot is receiving unexpected HTML instead of a proper JSON response. This often happens when there's an auth/session issue or network misconfiguration.

Here’s what you can try:

• Sign out and back in to both GitHub Desktop and Visual Studio (with the same account linked to Copilot Pro).

• Check for updates:
  Visual Studio 2022 (make sure it's fully updated)
  GitHub Copilot extension

• Temporarily disable VPN/Proxy if you're using one — sometimes it blocks or rewrites API responses.

• Clear the Copilot cache in Visual Studio:
  Go to %AppData%\Code\User\globalStorage\github.copilot
  Delete the folder and restart VS.

• If nothing works, try disabling “Use Default Proxy” (some logs suggest this was toggled).

Hopefully GitHub rolls out a backend fix soon, but these steps should get you unblocked. Let me know if any part needs elaboration!

This is massive problem.

Why a website? I need Copilot to work specifically with VS.
