This bug prevents me from using Apple Music

I have an iPhone 12 (running on iOS 15.6). Yesterday I discovered that I can’t use Apple Music because of the notification that “freezes” the app (unfortunately, I can’t attach a screenshot here).

I tried rebooting my iPhone, force restarting an app, and contacting with Apple Support. They advised me to reinstall the app and check if the problem persists. I did so, but not only the problem didn’t disappear, but a new one appeared. I can’t connect to my iCloud Music Library.

Please help me solve this annoying problem.

P.S. A week before I switched to Apple One (Family subscription). It’s not the first time I buy it.
