We are getting the same issue here with the win10 Photos App.
It now works for some users and not others on the same computer.
When you double click a file to open it fires up with a black (not blank) page then crashes. The windows logs show it crashes with an error ID 1000 and the program reports "file system error (-2147219196)".
We have tried removing the profile and any reg settings relevant so it loads a fresh profile and still the same.
Some have said its windows update KB4345421 but that is not installed. Others are saying to re-install the app. Cant see how that would be if it works for some people on the same computer.
I was wondering if it was a windows update and if you are getting it as well around the same time then it is very likely.
Time to start uninstalling updates?
