That's a pity, it can fix a lot of things. I think you should be able do the preparatory steps remotely - downloading the ISO, mount it and even run setup.exe to start the upgrade. After that your Dad's on his own (and you'll not have remote access until it's finished).
You know his abilities, I'll leave it up to you to decide if it's worth a try.
Other option to consider. Uninstall MS Photo App and use Windows Photo Viewer instead.
Restore Windows Photo Viewer in Windows 10 Windows 10 Tutorials
This behaviour does sound very similar to the problem i had just a moment ago.
For me the crash is caused by an update of the ms photo app.
You may be able to test if this is the case by creating a new local account and see if the app works on there for the first few minutes.
If this is the case I solved the issue by doing a system restore to ~ 2-3 days ago and than disabling automatic app updates in the windows store as fast as possible. It is important here that you disable the updates before windows automaticly updates the app.
