One way of resolving this.
Since you apply a force the pin is free to rotate perhaps, and hence that can be not solved (rigid body motion). Normally it is better from a solver point of view (to avoid this error), to apply remote displacements instead of forces and restrain say the rotation say in z (about axis of pin) to prevent that and push it up or down in the direction of the force.To get the force applied then we just look at the reaction (remote. displ.).

If one does not want to use the above, we can move the pins closer to the edge of the hole since there is no point in resolving the movement across the gap which is a rigid body movement and use adjust to touch in the contact settings. There are likely lots of tutorials on the internet to see how to deal with this.

All the best
