Apple Music on MacOS 12.4

I want to download songs on my MacBook so that I can listen to the songs offline. The problem I am now facing is that my MacBook is logged in to my main Apple ID(eg. A email). My apple music ac is using my second email which is for Japan region stuff(eg. B email). When I try to download the music on my MacBook, there is a message that "This device is linked to another Apple ID". There are only two buttons for me to choose, "Cancel" and "Transfer". I clicked the "Transfer" button, then I received a message "There was a temporary problem completing your request. An unknown error occurred (1001)". I tried to search it on Google but there is no similar case. Is there anyone who can help??
