Looks like, problemis with user's system (Blender)!
@Taylor-Henson Can you please! Try in same file, by making another rig?

Then try to Generate Rig Is work for you? (mine is working)
If you got same error, then please!
Try with Load Factory Setting, Enable Rigify...
Let we know!!!

This happens when trying to copy bones which have python-created custom properties, but no matching ui_props. In this instance the offending properties most likely come from the blender_mmd_tools add-on.
