Fix GitAuthError

✅ Solution

GitAuthError in DVC usually indicates authentication problems when DVC tries to interact with a remote Git repository, often because of SSH key issues or proxy configurations. Ensure your SSH key is properly configured and added to your SSH agent, and that your `dvc remote` and Git configurations have the correct URL using SSH instead of HTTPS. If using a proxy, properly set up your `http_proxy` and `https_proxy` environment variables or Git's proxy settings to allow DVC and Git to communicate through the proxy server.
