Lightroom started crashing!

[jowe380]

Hello, everyone. First time I'm posting in the forum, so please let me know if I need to share more information about my case. I need help because my lightroom started crashing and I don't know what to do, I'm quite desperate!

I have Lightroom 6.14 installed in my Macbook (macOS High Sierra 10.13.6, 15-inch Mid 2012 model, 2,3 GHz Intel Core i7, 500gb solid state drive, 16GB ram) and I have my photos in a 4TB external hard drive because my laptop hard drive does not have enough space. I have around 40k photos taking ~500GB. I also use Carbon Copy Cloner to make a backup of that hard drive into another 4GB hard drive. I only keep the catalog file and the preview file in my laptop hard drive.

My Lightroom has rarely crashed since many years ago when I started using it, until today when I was importing some photos from my computer HD into the 4TB hard drive and it crashed with the message "Lightroom quit unexpectedly" (error log is attached) Those were photos I transferred from my phone to the computer (using the mac Photos app) and then was transferring from the computer to the 4TB HD through Lightroom using the Import feature. After crashing for the first time, now it crashes constantly, sometimes just after the software starts, sometimes after some time using.

I notice that if I disconnect the 4TB hard drive and open Lightroom (it loses track of the photos because the HD is disconnected, but I still can see the previews), it does not crash at all. I also noticed that if I click on "find missing folder" and point it to the 4TB Backup HDD, the same problems with crashing happens. I thought it could be a physical damage of the main 4TB HD but because it happens with the backup HD, I imagine it's not.

Does anyone have any suggestions on why this is happening and how I could solve the problem? I thought about remaking the catalog from zero, but then I lose my collections and all the metadata from the photos (stars, flags, keywords, etc), which would be a disaster. Any suggestions are appreciated!

Thanks in advance

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the second link.

Another step is to try to reset the Lightroom preferences.

After trying the suggestions shared, turning off the face recognition solved the issue! Thanks
