Preview in iPhoto not working after editing the picture

My photos normally pre/view in the Photo app. However, change occured after one of recent system updates. If I edit/adjust a picture, it no longer previews and I can view it only in edit mode.

This problem applies to both our comps - one with Catalina and the other one with Big Sur.

I have already changed the photo card in my camera (SDHC) as well as the card reader, but the problem persists.

Thanks for help.

Mac mini, macOS 10.15

Hi


Can I guess that you are editing raw files?

If so this seems to be a bug I was experiencing also - If it is the same problem I am seeing, reverting edits to original will bring the image back to normal - after which you can edit again without problems.


The workaround I used was:

Import the raw files

Select them all (in all photos view)

CMD-E (auto enhance)

Image menu>Revert to original (while they are all still selected)


From then on they all work fine.


(seems to be fixed in Big Sur - for my raw files at least)
