It is totally frustrating that LR keeps freezing up. When I edit a photo it freezing or when I get the editing done on a photo it freezing during export. Paying for a service that does not work properly is not what I expected. Everything has been updated and even reinstalled but it still keeps happening.
We're sorry about the experience due to the app freezing while exporting.
Please share the version of Lightroom along with your computer's OS. Does the app freezes while exporting a specific image? Where are you trying to export the image? Does it help if you remove all external drives, cards or phone from your computer and then try exporting to your desktop?
