For the Kon, download a shader of your choice, some toon shader would look the best. Don't really know much about shaders myself but I use poiyomi. The purple texture stuff is most likely because of a missing shader or no textures, in your case it should only be because of the shader. Click on Kon once so it is highlighted in blue, then again so it's orange(the body), change the shader to the one you downloaded and imported. Should be fine now

As for dynamic bones, you'll have to look through all the parts on your avatar and see if it has a dynamic bone script attached to it. Remove them or get dynamic bones. Don't know if this works since I just copied it from my assets but here it is https://files.catbox.moe/c7hgnl.rar
