what should do ?

You can try reinstalling the current version of iTunes from https://www.apple.com/itunes/download/ over the top of the existing one. Or see this guide to uninstall iTunes from a Mac: https://www.inforaid.com/how-to-uninstall-itunes-from-mac-os-x-best-method/ then restore one of these recent builds direct from Apple's secure servers:

See also Empty/corrupt iTunes library after upgrade/crash for steps to roll back to the pre upgrade version of your iTunes database if required. Note iTunes 12.7 may have rearranged any iTunes U content into Podcasts or other sections of the library.
