Export entire library with originals on macOS

Hi, I'm trying to export all of my originals, about 10,000 images in my Lightroom library. I've tried many times but Lightroom consistently fails to complete the export for one reason or the other. I do a Select All > Export on all photos or even just a large album and after a while it fails to complete. I am exporting to a local hard drive and have the latest Lightroom version and macOS version on my Mac mini desktop. I've also tried accessing my library via Creative Cloud but it does not show up there. Thank you.
