Hello WuraolaO,
Are you unable to launch/open the Music app and receive this error? If so, then we'd recommend testing this further by booting to safe mode: How to use safe mode on your Mac Booting there will do a disk check, and prevent some apps or extensions from working. After testing the issue in safe mode, you can restart normally from the Apple menu > Restart and test the issue again in a normal boot.
Here's how to boot to safe mode:
How to use safe mode on your Mac
Safe mode can help you to determine whether an issue is caused by software that loads as your Mac starts up.
Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
Safe mode is particularly useful when you're trying to resolve an issue that doesn't seem to be associated with using any particular app. As always, keeping your software up to date is the first step toward resolving any software issue.

You can also use sections, 'If the issue continues in safe mode' and 'If the issue doesn't continue in safe mode' depending on your results there for a solution.
Hoping to hear how it goes, take care.
