Unable to create object

One of my user roles is unable to create a new object. The object is a Person that is inherited from Account. The userrole has all CRUD access to the entity and is assigned Administration and System admin roles, yet when clicking the ‘New’ button I receive an error message Creating object of type Registration.Person failed for security reasons ??? I also have another userrole that CAN create new Persons.

Issue is caused by the manage roles settings probably.

The user role probably has the setting for the manage users with roles set to none.
