I have also tried running Photoshop as am Admin as well as selecting Photoshop when right-clicking on a file and choosing it through the "Open With" options.
So far nothing seems to work. I'm hoping someone can give me a hand.
You're running Windows, right? Which version? What happens when you try to open these files? What does Open With report back? Are you just not seeing PS in the list of options for Open With? What about when PS is launched? Can you click Open and choose the file?
Thank you for the reply.
1)I'm running Windows 10 Home edition with the latest update installed.
2)When I click on a file with "Open" I'm prompted to select (for example) the image I wish to open. Once I select the image and hit the "Open" button the window closes and nothing opens.
3)Using right-click "Open With" bring the Photoshop window into focus, but again, nothing opens.
4)PS is appearing in the list of software to open with, it just doesn't succeed in opening the image as mentioned in 3)
5)There is no difference between trying to open a file when PS is launched or closed. Nor does opening the file through PS work.
I hope my answers were clear. Thanks for your help :)
Some other things to try:
Make sure your discreet Radeon graphics driver is up to date
Assign the High Performance graphics card to Photoshop rather than Integrated Graphics or Power Saving graphics card.

If you cannot open any file or cannot create a new one in Photoshop CC 2017 please try this workaround
Under Preferences > General
deactivate option 'Show "Start" workspace when no documents are open'
activate 'Show "Recent files" workspace when opening a file'
activate 'Use legacy "New document" interface'
and restart Photoshop.
Please write a short feedback if these steps solved the problem with opening or creating a new document.
Possibly the same or similar bug, PS stops opening or creating new files out of nowhere (maybe after some time of not being used/opened).
Everytime I am able to "fix" this by pressing Ctrl+Shift+Break key combination inside PS, either once, or several time, once per consecutive startup of PS. Not sure what this does but this has been my go-to solution for almost a decade - this was happenning in CS5.5/6 for years, although not so often!
