Unity Animation and Avatar problems galore

So after pulling my hair out I’ve come back with another problem: The avatar system keeps breaking all of my animations. For some reason every time I open unity after working, it tells me all of my animation clips need the avatar to be updated once again. If I don’t update it it works fine, but if I do, even though nothing has changed, it breaks everything and the animations don’t play. Even new animations that I am importing in proper format won’t play. What on earth is going on here? I am using the 2020.3.1 version of unity and Maya 2020 using the game exporter.

Alright I tried that and it didn’t work. Tried binary FBX and ASCII, different year versions. Finally I just rebuilt the main avatar and now the older animations work again, but the new ones the character collapses into a ball in the center.
