It’s the edges that take the time to render for export anyway. With more than 2.2 million edges in the model, it’s no wonder exporting is taking a long time.
You should clean up the model and simplify it. Also fix incorrect tag usage.
I also ran the CG Impact report plugin to check heavy components and groups, one chair alone has over 30K entities and you have 45 on the model, the table cloth has 18K entities and there are 9 on the model, that’s a lot to process, even if you have the current most powerful commercial cpu it will take a lot of time to export.
I recommend you to visit the sketchup campus website first to learn how to model, use groups, components and tags properly. SketchUp Campus
