I'm on about a year old Retina display iMac, running the latest and updated Photoshop CC. For a couple weeks now (it's happening more and more frequently), after using Photoshop for a while (time, and amount of usage varies), I'll open a file in a new tab, and it won't be active. The display and navigator and layers- everything I can see about the file will be for a file that was already open in a tab, except I can't manipulate it at all. I can work on the original tab, but any other files opened only show the information for that first file, and seems to be frozen. I can switch between file tabs (the tab highlights at any rate), but nothing changes. The only way I have been able to fix this is to shut down Photoshop then reopen it. When I've done that, Photoshop works fine for a while, but out of the blue, I will open a new file or files, and it's the same issue all over again.
Could you please let us know which version of Photoshop are you using & which operating system are you working on?
Also, please try resetting the preferences of Photoshop & let us know if it helps: Learn how to work with the MacBook Pro Touch Bar in Photoshop.
If the above suggestion doesn't work then try the steps mentioned on this article: Optimize performance Photoshop CC
Thank you for the reply.

Same issue! Cannot find help anywhere.

this also happens on my 27" iMac. Both machines, same Adobe CC account, running latest version of PS, and both have this exact same issue. It now happens every single day, sometimes twice per day.
Same issue here and it's getting very frequent. Have to restart every time.

Yeah it's frustrating paying for a product, and not having proper support. This has been a persistent issue going back through the last 2 updates, and nothing has changed. No word from Adobe anywhere on this.
Just gotta keep saving your work (or autosave), and hope you dont lose progress. It's extremely hard when you're a professional, working on simultaneous tabs and the glitch occurs. No way at all to switch between tabs and figure out what needs saved or not.
I have ruined so many documents and lost hours of time over the last 5-6 months because of this.
WORKAROUND that works for me. My computer: 2019 Macbook Pro, 16" Latest MacOS Update10.15.4 Photoshop CC 2020. PROBLEM: Have multiple tabs open and then I get a glitch that won't let me see other tabs - I only see one image that stays on screen as I try to open other tabs. I switch to other tabs but the smae image stays on screen. SOLUTION: Drag the working tab off screen to open its own window, away from the main photoshop display interface. Wait a while/a few seconds and the other tabs reappear and work again. Drag the tab back to the main interface and continue.
My workaround is to just open my window a touch, and all of a sudden my tab shows up. Adobe doesn't have an answer for this? So frustrating!!
