Hello Daniel, success!
I made one important change, and that was to replace this Frictionless contact with a cylindrical joint.Â
The reason that change is important can most easily be understood when meshing with a very coarse mesh, which I was forced to do because I was solving on the Student license that has a node count limit. Look at the brown pin in the hole in the gray part. It looks like an Allen wrench in a socket head cap screw. It does not allow rotation. By replacing Frictionless contact with a Cylindrical Joint, the pin is free to rotate in the hole.
