[Guide] Ripping models from Sketchfab

hey all, so i have been using this methord perfectly fine for about a year but today i started having issues with a certain model, i was wondering if anyone would be able to help me either with downloading it for me or trying to understand whats going wrong?

It works fine for a bit then gives this error
