Typical reasons for an error here include:

* The parent directory does not exist, cannot be created, or disallows writing.

* The persistent store is not accessible, due to permissions or data protection when the device is locked.

* The device is out of space.

* The store could not be migrated to the current model version.

Check the error message to determine what the actual problem was.
