You had enabled the option to render as hybrid the viewports, I disabled it and the export took 1 second. Here are the files.

I also fixed some incorrect tag usage and purged the file, it’s almost 50% lighter than the ones you shared. I deleted all the 3D people but if you prefer having them you can get them back from your original file. There are still a lot of assets that could be replaced with low poly ones, on the enscape assets library there are almost all the objects you used as assets but low poly, most of your assets are components with a lot of instances or groups that can still converted to components, so if you edit one component delete the object and replace with a low poly proxy all of them will be changed, if you want I can do that but I’ll do it in the afternoon.
