Occasionally - and randomly - when I try to open a PSD, TIF, JPG, etc. file either from the home screen, shortcut keystroke, file menu or by double-clicking on the file I get a blank screen, even though the file is open. When I "close" the blank screen with shortcut keystroke or by clicking the red dot in the upper-left, I get the home scree again, showing the file I just tried to open as the first file in the list. When I click on it, same thing - no image. Just a blank screen - no toolbars. I have to close PS and reopen. This appears to happen randomly. The same file may be fine next time, but another file may have the same problem - one that didn't have the problem before. Restarting Photoshop works, but I don't think this is the way it was meant to function. This happens on the computer at work, as well as my computer at home (separate CC subscriptions).
