As for this issue, it could be something wrong happened between Spotify and this Spotify recorder. Could I confirm whether your Spotify app is being updated to the latest version currently, if yes, it could be something changed in the Spotify app. You can wait for the new release of the Spotify recorder you are using.
Or you can have a try of another specialized Spotify recorder, like DRmare Spotify Music Converter, it updates often to be compatible with the latest Spotify app.
