Sketchfab.com crashes when using Safari

When I load any page from Sketchfab with a model the browser crashes and quits.

The error message from Safari states:

A problem repeatedly occurred with “https://sketchfab.com/3d-models/31mm-fp-11823x-ipt-f68b3a4017a74a7e823bf85226b777e6”

I’m on a Macbook Pro Retina running Safari Version 12.1.1 on macOS Sierra.

Any thoughts? Searching the forums suggest past Safari bugs have already been fixed.

Thanks.
