How can I upload songs to my iCloud music library when I keep getting an unknown error occurred (4019) warning?

The error code 4019 keeps appearing on my MacBook Pro iTunes library. It is impossible to add songs to my iCloud music library. Has anyone encountered this problem and come up with a solution?

Try in the Safe Mode.


Safe Mode - About


Safe Mode Startup – El Capitan. also Sierra


If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply. This will show what is running on your computer. No personal information is shown.
