Anyone know a remedy? Reinstall? Corrupt files?

click here If you see error -54 - Apple Support

"click here If you see error -54 - Apple Support" is apparently for sync issues.

We are getting the error simply when opening the Apple Music app after the Sonoma 14.3.1 upgrade.

Even after resetting the library location, it still throws this error.

And the iPhone syncs perfectly.

So that Apple Support link is not applicable to this problem.
