Mixamo add-on for Blender 3.2.1 throws error when creating control rig (error log in post)

I just downloaded the Mixamo add-on for Blender and when I try to generate a control rig it throws an error. All settings are default and I use the Y-bot model downloaded straight from Mixamo. Does anyone know why this is happening?
