If the extension does not work right (missing pages, does not start, etc.), you can try the following to clean up cache files and get it working again:

  1. Uninstall the extension from VS Code.
  2. Go to the extensions templates cache folder and delete the CoreT folder - this is where cache for the Telerik extensions are kept:
    • on Windows, open %localappdata%
    • on Mac, open /Users/[user_name]/.local/share/
  3. Install the extension again.

If you see Response status code does not indicate success: 401 (Logon failed.)., then the Nuget.Config file in %APPDATA%\NuGet may contain invalid credentials or keys. For more information check the Nuget Install article or Nuget Setup with CLI article
