Lightroom issues with Nikon D850 files
I've recently started using the Nikon D750 and D850, I've been a Canon shooter for years, but a friend recently bought these cameras and I have been trying them out. Problem is, every time I use Lightroom Classic to edit the images from the D850 it crashes within a few minutes, not only that but also a lot of the time causes my entire computer to crash (iMac). I have also had a lot of trouble with importing images off the D850, each time it has taken me 3-4 attempts to import and also then loses the folder once they are imported. I have 1300 images from a wedding I am currently working on, once the photos finally imported, I edited 250 of them and then when I went back to them, the folder no longer existed, yet it wouldn't let me re-import (saying they were already there). Multiple errors have occurred whenever I have tried to import images from the D850, specifically: when importing images the import screen reads: 'preview unavailable' for every image, then if you proceed to import this error appears (attached) ' some import operations were not performed' and lists all the images. This has been an ongoing problem for the last 6 months, I'm all out of ideas. Lightroom is up-to-date.
Notes: Yes, I know how to use Lightroom - and I know I haven't imported the photos into a different folder and just 'can't find them' Lightroom System info attached. The images can be opened in Photoshop, just not Lightroom
