Unable to open Photoshop document "not a valid Photoshop Document"

Question

Hi,

I am struggling to open almost all of my slightly older files on my Adobe Programs.

When I try to open them I recieve a message saying "Could not open Untitled.psd because it it not a valid Photoshop Document." These are all documents saved previously from Photoshop.

I am also unable to upload the files to this post, I keep getting an error message saying "Correct the highlighted errors and try again. The attachment's untitled.psd content type (application/x-photoshop) does not match its file extension and has been removed." I have attatched screenshots.

I am using Photoshop v 23.5.1 and macOs Monterey version 12.5.1

How do I go about fixing this problem so that I am able to access my files?

Thanks in advance!

Start by removing the special characters from your file names (´).

Next, make sure Photoshop is listed in Mac OS system preferences/Security and Privacy/Full Disk Access.

Lastly are you certain these are .psd files and not another format .tif, etc. and the extension was changed outside of the application?
