How do I get 4.11 Anim Dynamics to work properly?

When I heard about Anim Dynamics in 4.11, I was excited to try it out.

I downloaded 4.11, and made a very simple skeletal mesh to test it out:

I also got the physics asset set up properly, as well.

When I plugged in the ‘Anim Dynamics’ node it, the entire thing explodes.

I messed with all the sliders trying to get it to work, but it always gives me this crazy rig explosion. Anyone know what I am doing wrong?
