recently I´ve come to this problem specifically related to photos, other files work fine.
When I want to open or copy photos stored in phone, Windows is unable to view them or copy them, when I want to preview photo it says "file appears to be damaged, corrupted, or is too large". Actually it isnt, because in phone, everything works fine. I was reading about similar problems on internet, but no solution.
Then I got the idea, it may be some kind of protection and uninstalled Prey app. After that files could be accessed. My phone is Moto G5 Lineage OS 14.1, installed latest Prey from Google play
