v6.2.12 - Cannot read properties of undefined (reading 'length')

[RuanAzevedo]

I'm learning R3F and when I tried to convert a .glb model from readyplayer.me using this tool, I'm getting this infinite loop on the browser:

Reproduction repo

Checkout the file https://github.com/RuanAzevedo/gltfjsx-bug-repro/blob/main/src/components/Experience.jsx for the following code:

// this one works fines
<primitive object={scene} />
// this one doesn't work
{/* <Avatar /> */}

Versions before 6.2.12 work fine (tested from 6.2.11 to 6.2.3).
I'm pretty new with this 3D stuff, but with some directions maybe I can investigate and send a PR.
