Unable to access Apple Music after subscribing on my Mac

Re: "Apple music subscription issues: Unable to access Apple Music after subscribing on my Mac"

If you can't dismiss that offer by clicking the small X towards the right near the top:

Try restarting your Mac (Choose Apple menu  in top menu bar > Click Restart) Wait for Mac to restart and sign back in to check if you can access the Music app now.

(ie: restarting deletes temporary files, re-establishes connections, may update the subscription changes you made, and often restores order if something is not working as expected.)

If you still need help:

Next: Check you are signed in to your Mac with the Apple Account you will use for Apple Music:

Eg: If you need to sign in:

1. "Choose Apple menu  > System Settings.
2. From the sidebar, click Sign in.
3. Enter your Apple Account email address or phone number and your password. If prompted, enter the six-digit verification code sent to your trusted device or phone number and complete sign in.
4. Learn what to do if you can’t sign in"

Next: In the Music app: see if you can "Click Sign In at the bottom-left corner of the Music window" : More info: Sign in to your Apple Account in Music on Mac - Apple Support

Still need help? : Maybe you want to try clicking that big red button at the bottom in your screen shot, and perhaps Music app will check, realise you are already a subscriber, and allow you access.
