Ever since I upgraded to Catalina on my MacBook air, I have trouble with opening Pages. After opening a few, I receive a popup saying the file cannot be opened. NOW I am getting the same response with trying open a screen shot "The file xxxxxx.png couldn’t be opened". What is goin on? I need these tools on a daily basis (and there is no point attaching the sheet shot here, since it can't be opened)
MacBook Air 13", macOS 10.15
I've never changed permissions. Something happened to my files and ability to open many after upgrading to Catalina. I wish I could go back to the previous OS ... do you know if I can and which it was?

I've just tried out the earlier 'solution' (https://support.apple.com/en-gb/HT203538) which includes typing code using the Terminal App.
Using Apple was an escape from such dated (MS-DOS) procedures for those who used Apple kit simply to 'do' things.
Have I missed something, I can't believe that Apple would not fix this.
Someone please tell me: itsa me, not Apple !
(or should I reverse into Win10 ?)
Someone posted in another forum this solution, which has worked for me. I can now open numbers files, pages, .png sheet shots. 'course, it's only day one :)
This should do the trick.
I never changed them either, but this solved that same problem on my mac after upgrading to Catalina.
I think that you can downgrade if you want. If I find the link I will post it here.
I'll give Cata some more chances...
OH MY GOODNESS - your solution worked (so far). I am able to open files I was unable to open before ... and while I sometimes could open files for a period of time (hours, not days), I would often have to reboot when I started getting the pop-up. I am encouraged that I am able now (after rebooking, however) to open the screenshot .png that i was unable to open earlier.
Thank you for the link and for explaining to me that you hadn't changed any Permissions either!
try this..
well, thank you for your suggestion, which worked FOR ONE DAY. After changing permissions, I am now back to being unable to open .png screenshots. I AM NOT A HAPPY CAMPER WITH THIS CATALINA OS !!
sdly, that's why i did above .. it worked for one day ... I still cannot open .png screenshots :(
You are right. The elaborate permission changes stopped working.
So I just tried the above (Activity Monitor) solution and it worked.
I just hope it continues to work.
Thank you for posting this.
This solution stopped working too. Have to repeatedly do the Activity Monitor thing.
Not happy!
Same problem, screenshots opened yesterday, don't open today.
Hey Apple, it's 4th Dec, the first post on this was 14th Nov, when will Apple a) reply to these posts giving users hope; and b) fix it?
This will mess up your home directory if the process stops working part way through, as just happened to me. ("Ownership of the affected disk is required.")
Totally solved with the last update (10.15.2)
screen shot .png couldn’t be opened in Catalina
