Copying Photos to Computer Incomplete

So I thought I would determine if this was a phone issue or computer issue. I installed iTunes on another Windows 10 computer, all maintenance applied, no Malwarebytes, updated iTunes to latest and ran copy.

Coped at the folder level. Sure enough it copied up to IMG_4934, pause and failed. No error message, the copy box just disappeared as it does in any Windows copy task when the copy is complete.

So this is not a computer (machine level) issue. Could be a Windows issue, more likely an iOS 16 bug.

Thanks for responding.

I called Apple and explained the situation. They suggested I reset the network settings to clear any residual VPN leftovers. ( I had deleted the VPN app several responses back.)

After that they couldn't help. Suggested I call Microsoft. I reminded them they won't have any abilities to see into phone. Apple was unprepared to look at the data on the phone. I asked if they could run a trace on the copy process, NO.

So basically it is my problem. Outstanding support from one of the world's largest technology companies.

Thanks again to everyone who responded. Appreciate your time.

Thanks for responding.

There appears to be no corruption, at least that is obvious. The file it stops at, IMG_4935, copies fine. So does IMG_4934. The copy stops when I copy a large range of files that includes IMG_4934 and IMG_4935. So say if I copy IMG_4925 through IMG_4940.

I don't think this has ever happen before. That said if one or two files are missing when you copy hundreds, especially at the folder level there is no way to tell unless you audit each folder.

I caught it this time as the progress bar was about one third across the complete bar when it just just disappeared. That had me questioning status so I audited.

I don't believe this has ever happened before as I have copied large folders, vacation pictures, and no large swath of files were missing. In this case there were 112 pictures missing, so several days. I would have noticed this once I started to view on computer.

Thanks very much for your reply.

So I went to my iPhone and I deleted my VPN app. I then went to my Windows computer and I quit Malwarebytes. I checked I have the latest version of iTunes installed, I do, V 12.12.9

Yes iCloud photos is turned on and yes I keep originals on my phone.

Reran copy and it still fails. Interestingly it always fails at the same photo. Image 4935. (IMG_4935). Nothing special that I can see about this picture, just a statue, 6.3MB. I tried several times and once it skipped 4935 and 4936 but copied 165 of the 167 photos. So it is something about image 4935 ??

I even tried starting the copying from IMG_4934 to end. Only got two images, 4934 and the last. So then I tried starting the copying from IMG_4935 to end. It copied everything.

Not sure what this is telling me. Is it IMG_4935 or how the hand off between copying IMG_4934 and IMG_4935 is handled?

I should add that none of these pictures have been edited on phone and I don't use "Live". When I transfer photos I have the setting "Automatic" selected in Photos settings. (Late edit - I tried again with Keep Originals - so rather than jpg's it transfers in Apple format (HEIC) and it still fails at 4935)

What ever it is it is consistent.

Now I do have all 167 photos on my Windows computer and I can copy the complete folder within windows without issue. So it is something about copying from phone and the handshakes that are going on between these devices.

I don't use Windows Import.
