Yes Snapseed worked for me by saving a copy. Messaging a photo to myself and then saving said photo worked as well.
Hope this helps.
None of my photos from my Canon and Sony cameras loaded in Photos nor could I edit them, unless I used Snapseed or messaged the photo to myself.
But since the latest update iOS13.3 I noticed that any new photo I imported to my Photos, the photo was able to be opened and edited.
There were still many of my Canon and Sony photos that wouldn't load, open or able to be edited even with the latest update. So what I did, I deleted all those photos which I had uploaded to my iPhone from iCloud.com. These photos remained a problem and I was getting tired of waiting for a fix!
Once I updated to iOS 13.3 I then re uploaded my Canon and Sony photos to my iPhone via iCloud.com and these photos now open. Even my Photoshop artwork opens in Photos, which they used to in iOS 12. iOS 13 screwed everything up.
I don't know how long Apple engineers will take to fix that bug which seems to affect some photos after the iOS 13 update. The support team contacted me a couple of weeks ago and still no fix and no news.
