Unity Randomly Breaks When I Import A Prefab of An Avatar

So…this was a model I recently made and stuffs. I was just transferring it to a newer project, because the Inspector on Unity completely breaks, and I can’t restore it.

This happened recently to at least 3 of my Unity Projects that are VRChat Avatar related. I uninstalled the packages I was using to make some of my avatars. That includes VRCFury. I do not know if it is a VRCSDK issue. I’ve been trying to search for solutions, but there literally isn’t anything about it so far.

So far, I’m only shown a preview of the model in the Inspector. But the Inspector doesn’t allow me to make changes to the model (A.K.A. changing Generic to Humanoid, etc all that stuff).

Again, I’m not sure if this is a Unity issue or VRCSDK issue. I just create avatars without having to worry much about looking on the console ever so often. Now, this is just annoying me lol.

I was able to upload this avatar a day before this broke. So, I don’t know…
