RAW photos become blurry/corrupt after edit

Upon editing a RAW photo, it becomes blurry and corrupt (e.g., can't be shared/uploaded into an album) even after waiting days. Reverting to original makes it work again and the photo becomes crisp again, but of course loses any of those edits. I'm only able to export the edited photo as a jpg to get a working copy of the edited photo (in that case it is no longer blurry). Of note, the thumbnail in Photos does not look blurry. The OS is up to date and no software updates are pending. I see other users are having this same problem.

iMac 24″, macOS 12.6

RAWs from a Nikon DLSR. The library is on an external thunderbolt drive. Photos is Version 7.0 (460.0.120) and macOS is 12.6.1. I've had this setup for about 7 years without problem...until recently.

I'm having this issue also. I've got a 14" M1 Max and a Sony a7Riii. It's been happening since I got the Mac, even over multiple software updates, both on the OS and Photos side. The only fix has been to use my M1 iPad Pro instead, which is very frustrating considering the MacBook Pro cost over $4k. It seems to not be an issue with a particular raw file type, or even a particular OS or Photos version.

In my case, my Photos library is on the internal drive and it’s formatted as it was delivered from Apple. Raw photos edited on my iPad, which are synced to my Mac via iCloud, open fine on the Mac. Only if the edits originate on the Mac is there an issue.
