ImportMeshAsync error

It does not. For reference, previous answers to this question centered around something wrong with the loader import:

It looks like maybe you’re missing the GLTF loader. After you install the package “@babylonjs/loaders” then you can import GLTF loading support like below.

import "@babylonjs/loaders/glTF";

Turns out it was a version mismatch with the babylonjs preview npm packages and 4.2.1

removing the preview package dependencies and updating the versions worked

However, as far as I can tell, I do not have a version mismatch and am importing the correct plugin.
