Getting error when opening all PDFs "Adobe Acrobat could not open 'file' because it is

Hi when i go to open any PDF now with double click or "Open with" i get the following error

 

Adobe Acrobat could not open '20220322_&flow.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).

 

This has only started recently and is causing me serious problems.

 

Im using a Macbool Pro Monterey and Adobe Acrobat Pro DC Version 2022.001.20085.

 

Any advice woudl be really appreciated.

 

Sean

    Open the file in a plain-text editor, like Notepad. What's the first line you see there?

    I have this problem too, and when I open the file in Notepad, the first - the ONLY - line says "{"fromReader":false}"


    Then it's not a PDF file. Something went wrong when you downloaded it.
