Apply a Mesh Sizing control to all line bodies that have Link/Truss elements and set the Number of Elements to 1.

Having more than one Link element between the endpoints makes the stiffness matrix ill-conditioned for solving.

There should only be a single line body between the beam vertices that is assigned Link/Truss as multiple line bodies will create the same problem.
