The fix is to manually remove the GitHub Copilot login preferences from your VS Code settings.json.

Steps:

1. Open the command palette (Cmd+Shift+P or Ctrl+Shift+P)

2. Choose Preferences: Open Settings (JSON)

3. Look for this block:

   "github.copilot.advanced": {
     "serverUrl": "https://yourcompany.ghe.com"
   }
