iPhone Disappearing When Attempting to Import to Photos App on Mac

I saw other's struggling with this same issue and saw someone suggested that the issue was with the transfer of the videos, not the photos. An easy workaround is going to the 'video' folder in the 'media type' section of the photos app on the iPhone, selecting and deleting all (temporarily), then proceeding with the import of the photos to the Mac with no issues. You can then go into Recently Deleted and recover all the videos to add back to camera roll. Then, if you still wish to move the videos to the Mac, Airdrop in small batches of 50 or so at a time. Definitely not ideal, but it got the job done for me!
