Now that your trial has expired you may have only sample tracks available in the app, at 320k and with a (30 second?) time limitation. But it seems to me you ought to be able to get into the beta now, and I wonder if you can do that by contacting customer service rather than getting in line via the normal beta sign-up page. For most other issues with the Windows app, the Qobuz USA product manager has promised that the next update will improve performance. I take it that means an update numbered higher than the version 5.0.2 we currently have, and not the small build update I received today.
