Could you please let us know which version of Photoshop are you using?

This is a bit unclear - do you still have CC2017 installed? IOW you unchecked "remove old versions" in the CC installer? Does it behave normally?
Please - If you're saying they should check "remove old versions", you should say that.
I apologize for the misunderstanding.
my name is Alexis, and I've been experiencing the same. I have Photoshop and Lightroom 2018. Until last week, I was able to drag any file (.JPG) into the work space of both softwares and start working on them right away. Now The software will open but never display any file on the work space. Everytime I minimize and maximize the window size of the software, it will glitch and start creating a mess on the window space mixing tool bars on the crashed window.
I've tried unistalled and reinstalled the software already but with no success. Please get back to me ASAP.
I am having a similar problem with the most recent Photoshop CC 2018 update.
When I am in Lightroom and try to edit a file in Photoshop the PS program opens and a file tab appears at the top right corner of the image area but the picture does not display and I am unable to work on it. I uninstalled the app and reinstalled it but continue to have the problem.
The same thing happens if I go to either a jpg or a tiff file in my file folders and try to open it by double clicking it. Photoshop opens but I still get the same issue with only a file open tab showing up. This also happens if I try to open either of these two types of files directly from Photoshop.
If I try to open a cr2 image the file will initially open in bridge but when I click done it reverts to the previous problem in Photoshop.
How can these issues be fixed.
I have had this problem since December with PS cc updates.
I uninstalled and went back to 2016.
But today, I have found a solution I think!
When opening a file and nothing at all happens (as you all have seen), resize the photoshop window and hey presto the image is there.
I have to do this to see an open image every time at moment. Even when switching between open windows.
I'm on Mac pro and also Macbook pro running Sierra and High Sierra respectively,
That's a buggy video driver.
This can be manually updated from NVidia or AMD on Windows - but on Mac you have to wait for a driver update from Apple.
