In Movie Maker Player, when i try to set "Motion to Animgraph Parameters" for the ModelRenderer(skinned) with the human model (either human.vmdl or citizen_human_male.vmdl) i get the error message: 
Expected at least one block. (Parameter 'blocks')
System.ArgumentException: Expected at least one block. (Parameter 'blocks')

Is there any workaround?

I think it's worth to mention that applying "Motion to Animgraph Parameters" for the original citizen (Terry) works correctly and as described on the page "Skeletal Animation" in the Movie Maker documentation.
