Possible update issue and disappearing model

I have a few 3D models (Blender) on a wordpress woocommerce website and the model and/or the whole plugin view doesnt load in.

Its set up to add and take off products extras when chosen in the dropdown boxes. This means it ahs to be set up as a varibale product to have a price for each combination of extras chosen.

The model works fine as is should before adding prices to the variables. As soon as you add one price the whole thing just doesnt load in. All past models used are also now not loading in after working fine before.

I thought this could be because of the new Verge3D update so i went to do so and it is throwing up the error code shwon in the image.

What is this error and could this be the problem?

Any help will be much appreciated!
