I've never had a problem running Lightroom until now and just updated to the new OS so imagine that the problem is the OS update. Half of the pictures are now black.
When I try exporting an image that's black that I've already edited, the exported image is black. I checked and have the most recent update for Lightroom.
Is anyone else having this problem?
First, try disabling GPU in the Preferences (Performance tab). Any better?If not, recalibrate and build a new ICC display profile, the old one might be corrupted.If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. On the Mac, that's part of the OS update(s) so if this is the latest OS version, you may need to roll back a release.

Thanks for the suggestions.
I unchecked the GPU box under Performance and restarted the computer and it does seem to be working now.
Will using Lightroom with that box unchecked make any difference?
One other weird thing since the OS update:
The icon for Lightroom Classic no longer appears in the Dock.
