There was an error loading the model.

The white membrane can be previewed normally during the process, but after passing through the texture mapping node, it prompts me with "Error loading model". What could be causing this?

I also had that issue, and just deleted the Preview 3D node, adding a Export Mesh node (gets a trimesh as input, outputs a 3D format, such as GLB), then passing the output (GLB) to a preview 3D. I suppose there is something in the mesh pass-through or save code that is causing it but haven't really looked under the hood yet. Perhaps a hardcoded path, since in my case I'm running a few docker images. See if that works for you.
