Unable to make resource locally available
I use iCloud Library in Apple Photos to store now almost 30,000 photos. Recently when I've tried to share some of the older photos (from 1-3 years ago) I've been getting an error for about 10% of the photos "Unable to make resource locally available"
I can view the photo and it appears to load (the circle in the bottom right), but when I try to edit I get an error "Cannot Start Editing"
I've seen this topic come up in a few other threads, but the suggestions haven't worked for me. I tried rebuilding the library and I still get the issue.
Other things I've tried
- I am able to find these photos on iCloud.com/photos and share a link to them.
- I am able to load these photos on my iPhone—viewing, editing, and sharing.
Some details about my setup
- Apple Photos Version 5.0 (161.0.120)
- Catalina Version 10.15.7 (19H114)
- Running on a late 2013 MBP 15" Retina
- My library is managed (Copy items to the photo library) and located on the main harddrive
- I use iCloud Photos and optimize storage
- I don't use a VPN
