I'm having a similar problem with any model I try except for the default xbot one.
I tried a model which seemingly doesn't create any springs and it's the same ( https://hub.vroid.com/en/characters/7525675972481416401/models/92472199287818087... )
Here are the logs for trying to load this model https://gist.github.com/developedby/333445bbf7b2d99de172e3e3937c9853
