SOLUTION!
Hey everyone. I have this problem since September. I tried everything and every time my Photos App freezes while it scans for import from my iPhone.
First of all I tried the process to a new PC with the exact same windows (and photos) version only to find out it works normally and it is not an iOS issue.
What I did is this:
Press import as normal while you remember the number that your scan freezes and press "Cancel" once, before it reaches this number. Basically, dont let it freeze and press cancel in time. If it freezes, kill the task and launch again. Just a random number before the one it freezes works. After that, press import again and you will notice that the scan number continues from the one you pressed "cancel". But this time it will reach the max number and you will get to the "choose what to import" screen.
I tried the process 10 times exactly and it worked all times. This looks like a good workaround until the App gets fixed (maybe in November update?). Please try this and post.
This works for me but with multiple reboots of the iPhone to get all the photos. I had over 2500 photos to download.
My systems: Windows 10 Pro Version 1903 OS build 18362.449. Photo App 2019.19071.17920.0. iPhone 8 Plus with iOS 13.2.
Below are the things I have tried until I came across your solution!
1. Updated Windows program and apps (to update apps go to MS Store and update all apps there)
2. In Windows Apps and Features setting for Microsoft Photo and under Advanced settings, tried repair and reset the app. It didn’t work.
3. Updated iTunes to the latest revision
4. Updated iPhone to the latest revision
5. Tried different USB ports
6. Tried to download photos from another phone (iPhone 8), with a lot fewer photos, around 700 photos) and it worked.
7. Tried using the Windows Administrator account but still didn’t work
8. Tried download photos using Windows Explorer and using the Import Pictures and Video right-click context menu. This seems to work ok but had multiple errors about files not available or something like that (but doesn’t tell you which files!).
9. Switched on iPhone Photo app settings from "Automatic" to "Keep Originals" (this will download .heic files from iPhone). Still didn’t work.
10. At this point, tried your solution and it worked! Btw, using the Esc key is the same as using the Cancel button on the popup. After the cancel, tried to download again and the Photo app was able to move on to the next step – which is to allow one to choose which photos to download.
11. During the download process there were numerous errors with the “Something went wrong” and to try again popup. I had to shut down and reboot iPhone numerous times to get all the photos out.
Yes, I have been doing the above, downloading 0 to 50 photos / videos at a time. Switching off the iPhone & iPad to do some more. About to spend a second day trying to download my holiday photos. I have better things to do than this all day and night. It wasn't a problem for me before Windows 10, so what has changed.
I think we all show just buy a Apple computer (MacBook or other) so we don't have this trouble that Windows refuses to admit to and fix so we can use computers they way they should work, that is be a time saver!
