Cant apply an animation to my model

Hi,

I've tried two ways to apply a Mixamo animation to my model, I uploaded it to the site and when I try to use the auto-rigger it says "Unknown error while generating motion".

So i tried another way and clicked "Create Control Rig" in Blender, imported the animation and clicked "Apply Animation to Control Rig" but I get this error:

Python: Traceback (most recent call last):
