I'm having the same problem. Nothing suggested here has resolved the issue. 

I had the same issue with RAW files, so I reinstalled the 'Camera Raw' plugins

Did anyone figure this out yet?  Its happening to me also.  Trying to open a DDS and Im getting this same error.  This is new and Ive always been able to open up DDS before.  Thanks

i am having this problem trying to open an OBJ file in photoshop....

Had the same issue. Worked opening the same file from another PC and then saving as another file.

I'm having exactly the same problem with a couple of files - only just started a few weeks ago.

idk what file type you are attempting to use, i had this issue with a dds file. I converted it to a TGA file using a convertio, the file opened and we good. Not saying to use the website idk if its safe but def try converting the file and or redownloading it through something. Good luck

Try opening in Photoshop with the shift + opt/alt keys down to see if the merged composite is available.

Try other Adobe software. Lightroom, Bridge Export, placing the file into InDesign or Illustrator etc.

Try 3rd party software.

Good luck!

I have had exactly the same issue. Anyone know how I can recover this file, or at least a preview of it?

The only way you'd get that error is if

1. you are trying to open it from the home screen/recent files

or

2. you have linked objects (such as a smart object) that are unavailable.

Do you get a different error if you move it or using a different computer?
