This error can be avoided by either respecting the foreign key constraint or removing this constraint in the database.

The ContactPersonId in your Address table doesn't have a matching record in your ContactPerson table.

Make sure the ContactPerson is added first.

From the name (FK_Address_ContactPerson) and error it seems like your contact doesn't have an address.

Are you trying to insert a contact where the there is an invalid value in the the address id on the contact, but where the corresponding Address doesn't exist?
