“MPAssistantErrorDomain” error message when running Shortcuts related to Apple Music

I’m trying to run a Shortcut in iOS 15.6.1 that I use to select an Apple Music Radio station when my CarPlay connects. 

When I test run the shortcut, almost all the time, I’m getting an error message:

MPAssistantErrorDomain error 0

This is really annoying cause it stops the shortcut. 

I don’t know if it’s related, but for about a week or two, I’m often getting error messages when I try to go to the App Store, on in the Apple Music app. In App Store it’s loading for a good 30 sec then give me a “Impossible connection to App Store, retry” message. 

In the Music App, I get the “Impossible to create the station”. 

Any help would be appreciated. It looks like it’s related to my Apple account. 

Thanks
