R3F issue importing GLB with animations from ReadyPlayerMe and Blender

I exported a character from readyplayer.me as glb, which works fine in R3F.

I imported the model into Blender and transformed it into a FBX for mixamo.

After I selected the animations I liked I managed to export the model nicely with animations and it runs in the threejs Editor. ThreeJS Editor Screenshot all working fine

4 meshes however fail to work in the R3F imported glb. R3F Screenshot without Head and Eye Meshes

import { useAnimations, useGLTF } from '@react-three/drei'
import { useControls } from 'leva'
import React, { useEffect, useRef } from 'react'

export function AvatarWinter(props) {
  const group = useRef()
  const { nodes, materials, animations } = useGLTF('/models/avatar-winter.glb')
  const { actions } = useAnimations(animations, group)
  const { animation } = useControls("ANIMATION", {
    animation: {
      value: "Idle",
      options: Object.keys(actions)
    }
  })

  useEffect(() => {
    actions[animation].reset().fadeIn(0.5).play()
    return () => actions[animation].fadeOut(0.5)
  }, [animation])
  console.log(actions)
  return (

useGLTF.preload('/models/avatar-winter.glb')

The skeleton on meshes error message is the following:

Uncaught TypeError: Cannot read properties of undefined (reading 'length')

relating to the following line in threejs:

let morphInfluencesSum = 0;

            for ( let i = 0; i < objectInfluences.length; i ++ ) {

                morphInfluencesSum += objectInfluences[ i ];

            }

Perhapse somebody got a pointer to what I have to change in my blender export? Thanks Blender GLTF Export Settings Screenshot

Update 2024-02-13 I am using a workaround atm, which works but doesn't give me the versatility of the GLFT deconstruct. Using a 'primitive' instead works for the moment.
