Microsoft Photos: Unable to open files (error -2147219195)

A repair upgrade for single UWP Windows 10App  malfunctioning? I think the answer 'Windows 10 1803 is still work in progress, better wait for the official release and/or the next cumulative patch' would still have been more reasonable.

Sorry but this is a shockingly disproportionate suggestion.

I think you are in the mind set of repair upgrades being like those from the Windows 2000 Professional era where they are more risky.

If you prefer waiting out for the .5 cumulative update, you can do that as another option. You can also install a third party viewer such as Irfanview to see if you can open and view your photos.

But what you are seeing, I have suggested repair upgrades for and though it seems like overkill, it "has worked".

What I suggest you do is file a bug report in the Feedback hub and send me the short link so I can vote on it and bring it to the attention of the Photos engineers.

Make sure you send short link to them. They are known to be very responsive and might be able to point it in the right direction.

Short link: https://aka.ms/AA17jgl. Only caveat is, it's in French as my Hub App was forcefully installed in French, my System language. I hope this is no obstacle to your diligence.

I have the same issue. Exhausted all repair options.

Before I do a repair upgrade, which I assume will function similarly to factory state repair, I'm considering using Infranview, as MS Photos is a bloated software that amazingly managed to take up to 30% performance on my CPU (i5 8600k) which I found to be a little to much.

Is the corrupted file likely to cause trouble in other programs? I use a lot of visual software.

Is it a bearable choice to abandon solving this issue with MS Photos for now and just use different software for now?

I think a simple update of MS Photos from the MS Store fixed it. In case you have other issues that  a reinstall anyway, I would suggest doing an in-place upgrade from the Media Creation Tool available from the Windows support website. It bests all alternatives I've known so far if you already have Windows 10 installed as fixes all issues related to system files while leaving the non-system files (i.e. user files, including preferences, programs and documents) untouched.

Good luck!
