iTunes May be Corrupted, Technically:

So, Reinstall the macOS:

Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Command-R to reinstall the latest macOS that was installed on your Mac (recommended). Go Here: How to reinstall macOS from macOS Recovery - Apple Support

Important:

Create a Time Machine Backup, First:

Prior to the re-installation of your macOS, be certain to backup your Mac using a Time Machine Backup. That way, you can have something to restore your Mac from, should anything go wrong with the reinstall. Use an external hard drive that is at least 1.5 the total storage capacity.
