depending on the way those loaded components are connected, it looks like they don't have enough restraints, a small offset in load and they would spin around.
try adding a cylindrical restraint on them to see if you can push upwards at that angle and have stability
if that doesn't work. start with one part that is fixed and a gravity load. get it to run. then add another. and so on and so on until all your components and analysis elements are added.
Addition of a cylindrical restraint solved the problem. Thanks a lot Jared.
Your picture doesn't show the important information to answer the question.
It looks like 3 parts in your setup. The frame and 2 pins?
Have you defined contact between these parts or did you rely on the "global bonded" contact?
I guess the latter and that you have some sort of play between the parts so the global contact never kicked in.
If you instead add 2 "no penetration" contacts between pins and hinge and add a cylindrical restraint, as Jared mentioned, it should work.
Or if you just add 2 "bonded" contacts, in which case the 3 parts will act as one part.
I was in the same boat you're in myself today. I was trying to simulate a cantilevered beam made of 1/4" thick sheet metal welded to a long piece of angle iron and I was getting the same error you're getting (not necessarily for the same reasons). However I found that since Solidworks meshed the angle iron as a solid, but meshed the sheet metal as a face (2D mesh) the bonded constraints between the two became effectively zero. I changed the mesh on the sheet metal piece to treat as a solid, and voila it worked.
