How do I use the control rig picker? It isn't doing anything (UE 5.4.2)

Worked fine in 5.1, but 5.3 and 5.4 I am confused about how I am supposed to use the control rig picker (MH_CR_Picker editor widget). When I run it:

  1. I do not see any option to select the actor (there is nothing to choose in the drop down)
  2. Clicking on the parts of the body on the widget does not select the corresponding control shape.

Is there a particular way I am supposed to use it? I’ve made sure the metahuman BP is selected when running the widget. Does nothing.

Would really appreciate some help. I’m stumped, especially since in 5.1 it used to work fine for me (but I have to move to 5.3/5.4 for my ongoing work).
