Error: iOS needs to repair your library before open applications

Hi all,

I have just downloaded and installed the latest version of Garage Band in my MacBook Pro (recently updated to the last iOS High Sierra). When I try to open the app, a message pops up telling 'iOS needs to repair your library before open applications'. I click the 'repair' button; however, it seems nothing changes since Garage Band is not able to start and it quits suddenly.

Just wondering if anyone is experiencing the same issue, and possible ways to solve it. Thank you 🙂

MacBook Pro with Retina display, macOS High Sierra (10.13.1)

In similar cases it helped to disable iCloud for GarageBand. Can you launch GarageBand, if you disable iCloud in the Settings > Your Name > iCloud > GarageBand? You will no longer be able to access the Projects in iCloud, however.
