You can't be receiving anything other than a Unity package since VRCMods only allows the upload of Unity package files. Also, no, this avatar has not been updated because I'm lazy.
The package works in my Unity projects. It was made with a Patreon version of Poiyomi's toon shader so I had to downgrade to a previous version of his shader before I uploaded it here. That's what causes the issues for some people. It's an extremely easy fix and the issue doesn't occur for everyone though.
fun fact, while VRChat isn't very well optimized, having a better PC definitely lets you use whatever kind of dynamic bones you want :) shell out more money for a better PC dweebs. if you don't like the dynamic bones, turn them off in Unity. it's real easy. I made the model so that it would fall in the "Good" optimization category if all dynamic bones are turned off iirc.
