All I want to do is transfer my photos to my PC (or external drive) for backup. Why is this is such a painful task? It’s an iPhone SE, ios 17.1.1

I’ve tried the drag and drop method. No luck. Maybe 10 photos get transfered. I’ve tried the windows photo app method with import media from usb (iphone). It recognizes about 10% of the photos, imports them, and half of them are just partial grey boxes.

I maxed out my free cloud storage long ago - everything is stored locally on the phone and I just want to back these up.

How it is that we are in 2023 and I can’t just select all photos to transfer to my computer without a giant headache? Any tips would be appreciated… thank you.
