Updated to Sequoia 15.4.1 and cannot backup / import photos from iPhone 14 Pro to Photos app

The usual cause of an import failing is a corrupt file. How many pictures are you trying to import? Small batches may work until you get to the batch that includes the corrupt file.

Same here, also using iphone 14 pro. I have the photos library on an external drive. When I updated to Sequioa 15.4.1 it failed to open it saying it cannot "unlock" it and I had to browse and open it manually. When I did it proceeded to "update" the library.

Since then, when I try to import new photos from the phone, it momentarily disconnects the phone and reconnects it in the Photos app, and then the phone is unresponsive within the app. It fails to import even a single photo.

I had this before. Thanks for bringing it up, it seems to be the same problem actually. If I skip the first file in the queue, it is able to import the rest.

As far as I remember, in order to make the "Import New" useful again, I had airdropped the "corrupted file" to the computer, thus importing it that way, so it went away from the unimported files.

It might be best to get rid of this file in Photos. You could save it to files, delete it from Photos, and the save the files version to Photos.

I use other editing apps on the Mac, but I try to be careful to go through Photos' own processes for checking the compatibility of files. I'm not sure how that's done on in iOS, but anything that bypasses Photos' checks can lead to headaches, later. Unless I heartily believed the alternate editor's guarantees, I think I'd use Photos to export to Files, edit, and then use Save to Files to re-import.

Not necessarily the same. How is your external drive formatted?

It's APFS, and was working absolutely fine before updating to Sequioa 15.4.1.
