Can't open PSD or PNG files in PS 2020.

Question

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 (side note: no idea why I have so many versions in my CC). Once I open these files in the older version of PS, they then open fine in the latest PS 2020 (version 21.1.1)! A weird relief – however slightly annoying.

Is this a Photoshop 2020 issue or are these files actually corrupt?

Yes, if I open them in PS 2018 first they will then open in PS 2020. Its so strange, and a little inefficient. 😉

I can't place the PNG or PSD into Illustrator.
The PNG files don't open in Preview either.
I don't even see the preview image in Finder or Bridge - just the PS icon or Preview icon (for the PNGs). On the files - I can open I can see the preview.
I've cleaned my Mac and apparently no malware threats.

Thanks so much for all your suggestions! I'll reach out to the Adobe support to see if they can help.

Update from Adobe Support:

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

So it might be that I'm using Catalina, however they wouldn't really elaborate on what the issue was – it's just something to do with the file settings and metadata.

My solution (in case other people have this issue) is essentially what I was doing from the start: keep opening them in PS 2018 to then open them in PS 2020. Haha.

2018 and 2019 are a different build to the new 20 and 21 builds of Photoshop, Adobe busted the gpu drivers and that makes 3D stop working correct

if you do any 3d work then you should use one of the older builds but I can't tell you if the files are corupt with out share it for testing
