Apple Music PC Windows 11 stalls on loading

This question has been asked numerous times and is ROUTINELY IGNORED by Apple Tech Support. I have installed the Apple Music app on my PC, because the browser version is unreliable. I sign in and am recognized, but the Home page won't load, nor my playlists or anything else in my library. Nothing is visible except that infuriating circle chasing its own tail.

Why won't this app work? I run a symphony orchestra, ballet company, and opera company have built up enormous playlists and library. I rely on Apple Music in my business. But we can't use Macs on our system, so if this is a ploy to get PC users to switch to Mac, it won't work.

How can I get the app to work??
