Yes please submit your Lr crash report with your email address.

It could be a hardware issue (bad RAM memory/disk).

Since this doesn't happen to everyone, it's probably not a bug, but an OS issue on your Mac. I was a Mac IT pro for 25 years. It may be a corrupt cache or application state, or directory damage. Please give your Mac the "once over"! Run the free Onyx (https://www.titanium-software.fr/en/o...), reboot. (In Onyx just run almost everything in the Maintenance tab, deselecting things you may not want deleted, like Launch Services . Hit the "Options" button and deselect more stuff like Cookies & Other Site Data, Browser History, Form Values, etc.), then hit Run Tasks. After it's done it will ask for a reboot. 

If that doesn’t fix it run Disk Warrior if you can ($120), (https://www.alsoft.com), reboot. If you can’t do Disk Warrior, at least run First Aid from Disk Utility. Also just doing a "Safe Boot" can clear out caches (restart, hold down shift until you see "Safe Boot" on the screen, then reboot normally. 

If that doesn’t work try launching Lightroom from your other (admin or test) account, with a new catalog, as a test. Does it run OK? If it does it may be a corrupted preference in your Username/Library folder. Check The Lightroom Queen site for instructions on how to reset your preferences (https://www.lightroomqueen.com).

Let me know.

Thank you, I will try to do your recommendations and let you know how it goes. 

Looked at the two crash logs that you have submitted. Lr crashed at two different places but all seems related to reading JPEG previews from the preview cache db or Nikon raw files.

The macOS CoreGraphics API is implicated in one of the crashes. That is odd. I would say either the files are corrupted on the disk or there is some disk controller issues.

Given that you have created a brand new catalog and new set of photo files, and Lr still crashes. It is either the disk or the disk controller is flaky. Is the disk an internal drive? Try a new catalog and put it and the image assets on a different drive and see if it makes a difference. Is the cable secured?

I sent the computer to service. It is bad RAM, so they are changing the entire main board because the Ram is welded directly in the main board. Thank you for troubleshooting, I hope this will fix the issue.

Hi, I also have the same problem on iMac 27" 5K late 2015 I use 32gb RAM OWC.
From the beginning when I bought the iMac, I also ordered the extra ram memory that I replaced with the original one, I do not remember well enough, but I think it was a period when the problems started.
I thought it was a different kind of problem, namely that it was software or an operating system. After many upgrades, I realized that it was not a problem, and my negligence was well deserved because I did not wear the service until a few days ago.
Authorized service said that the diagnostics they did show no hardware errors. That is, everything is ok. 
Before going to the service I tried to test the ram memory myself by individually removing and returning it, I came to the conclusion that a single memory is problematic. However, after a few months, the problem continued. And I returned a memory that seemed problematic to me. 
I installed Windows 10 on iMac and also tried to export photos through it and the same problem happened, iMac restarted.
I tried several times to install a fresh system( from Siera to Catalina), everything was reset to factory settings and again there were problems with them.
Now I tried with external hard disk, to install OS on it and through it to try to export the photo, for now everything works ok, but it scares me not to be the same problem again as it was with ram memory, some time ok then after problems again.

Do you have any advice on what to do?

My problem was fixed when the dealer replaced the bad ram. Sorry, I don’t have any more advice for you.

I've reviewed the four crash reports associated with your email. They indicate you are using 9.2. Can you update to the latest, 9.2.1 and see if you are still crashing. I would recommend a clean install. 


Clean Classic Install Procedure

• Close Lightroom
• Restart the computer
• Use the Adobe Creative Cloud App to uninstall Lightroom Classic
• Restart the computer
• Install Lightroom Classic via the Creative Cloud App without launching any other programs.
• Restart the computer
• Launch Lightroom
• Wait 5 minutes 

It's been a long time since I had the problem about 3 years, so I update to 9.2.1. I'm sure nothing will help. 
I think I found a problem, I'm still testing but I think it's a problem with RAM. 
I removed 16gb and there is 16gb left but 8 in A1 port and 8 in B1 port. That's just how I managed it to work, now whether it's a problem in RAM or the motherboard so the slots are bad, I don't know. For now, it works.
