Photoshop 21.1.2: Can't open PSD or PNG files

I created a PSD file in January 2020, and suddenly can no longer open some PSD or PNG files. I get a bunch of errors: 'its not a PNG file' or 'its not a valid Photoshop file'. Thinking they must be corrupt somehow.

However, these files open perfectly on PS 2018. Once I open these files in the older version of PS, they then open fine in the latest PS 2020 (version 21.1.1).


I originally posted about this in the Adobe Community Forum here: https://community.adobe.com/t5/photoshop/can-t-open-psd-or-png-files-in-ps-2020/m-p/11055432?page=1#...

After chatting with some members, and trying all their suggestions, I contacted Adobe Support who confirmed the following: 

"The files aren't corrupt as they are working fine in an older version of the application. This is a compatibility issue."

They advised I should continue to open the file in PS 2018 to then use them in PS 2020. 

I'm using:


  • Mac OS: Catalina 10.15.4
  • PS 2020: 21.1.2 (Creative Cloud) – and now also PS 2018 ;)

Can you post files you're having trouble with? 

I suspect the problem is the files actually have the wrong extension. See: https://helpx.adobe.com/photoshop/kb/error-invalid-jpeg-marker-displays.html

I believe someone from the other forum already tried that theory?

Files are here: https://www.dropbox.com/sh/46dfiuhf8z...

Both of these files open fine for me in CC 2020 on macOS 10.15.4. The only issue with Catalina and files was people accidentally saving files with the wrong extension. Seems like a system specific issue. I'm going to look at the agent notes a little bit, but files should be compatible backwards and forwards. The files should open and if there's any new layer types or blend modes, it should give you a warning but still open.

In the meantime, tne thing I might try as a quick test is create a new user admin account and try opening the files in Photoshop from the new admin user account.

These are both legit files and have the correct extension from what I can tell. Did any of the other troubleshooting help?

I tried all the troubleshooting ideas from the other forum and even ones via the supoprt chat, but still they won't open without me opening them in PS2018 first.

Saying that - I did try to open them on my other iMac (which has a new hard drive) and they opened fine.

So its something to do with this laptop that I'm on. Is it worth sharing my hardware information?

Ok. Did you try the new Admin user account like I suggested above? I don't think the hardware is to blame. Maybe user permissions, or some OS level issue (file associations).

It didn't work with the new user admin account - it just generated the same errors as before.

On the computer where it's not working correctly, what does the Open With field have in it in the File Info dialog in macOS?

The PSD creation/modified date has changed since I opened it on my iMac.

Maybe its something to do with the 'online-only' tag that I've just noticed?

Should also mention even though the PNG default is Preview - I have been trying to open it in PS. Preview also gives me the same errors.
