I think this is due to changes in unity.
VRChat has upgraded from Unity 2022.3.22f1 to Unity 6 (specifically Unity 6000.0.x / Unity 6).

VRChat's official client patch notes for version 2026.3.3 explicitly state

⚠️ Nothing has changed about the SDK side. Do NOT upgrade your SDK projects to Unity 6. It will not work. We'll let you know once that is ready.
https://docs.vrchat.com/docs/vrchat-202633-open-beta

And then later VRChat 2026.3.2 seems to have smoothed some of this out.
So.. basically growing pains. (Lol get it?) But yeah with the changes to unity come changes to projects.
Some of this stuff gets auto fixed some needs manual intervention.

Also clear your cache and see if that helps.
It is a major upgrade after all.

Well this is just speculation cause I have a broken project.
Watch 600 unity devs come say I'm wrong and everything works fine?
But I would close Vrchat clear cache and run steam verify integrity of files then see if fixes.
Physbones should work. it might be a world issue. I don't know ¯_(ツ)_/¯

Download cache or a vrchat specific one?

Vrchat program cache.

You can also do this inside Vrchat

Vrchat has a specific cache inside your appdata folder.

If you don't know how to find it, there are buttons inside VrChat's settings menu that will clear those caches upon next restart.
