"This is not a valid Portable Document File (PDF)..." random error in Photoshop

Explorer ,
Dec 26, 2019 Dec 26, 2019

For the past couple of months I've been getting this error: "this is not a valid Portable Document File (PDF) document. It cannot be opened." error when I'm NOT trying to open anything.  I'd say it's happened maybe 10 times over the last couple of months and 9 of those times, it's happened when I'm waking the computer from sleep.  I can't seem to figure out any pattern to it.  It's like it's trying to open a file on it's own but it doesn't show in the recent list and I'm not seeing any action that could be doing this.

 

Any ideas?

Same issue here. Photoshop is not the active software I'm using, nothing opened in Photoshop and still get the message randomly. 

 

Mac OS Monterey

Photoshop 24.7.0

 

Any fixes out there?

Just started getting this bug myself. It never happened before, but after upgrading to PS2024 a week or two ago I've been getting the random error message while working in other programs every few days. Full Disc Access is enabled.

 

Photoshop 25.3.1

Ventura 13.6.3

I've been getting this message off and on over the years myself, and I'm not shocked to see that it hasn't been addressed. They'll throw every marketing and development resource at trying to get that generative AI microtransaction gravy train going, but stability and quality of life issues in Adobe applications? Not so much.

Now it's 2025, more than five years since the thread was started and more than 18 months since my post, and I'm still getting these alerts. The bug report obviously didn't help.

Oddly, I don't think I've seen this message for over a year. I'm running macOS 15.1 and macOS 15.2 on my machines, both with Photoshop 2025 v. 26.2. 

 

In one of the messages last year someone posted this solution. At the time, I thought that would only be a temporary fix since the clipboard would just be filled again. I did do it and I don't know, maybe that cleared out some other crap stuck up in there so its worth a try. Below is the fix to try:

 

"Emptying the clipboard (Edit=>Purge=>Clipboard) worked for me."

Hi, thanks, I have tried that but it didn't have any lasting effect for me.

Thanks for the tip. "Clipboard" is greyed out for me... So, nothing to clear yet I get the same error message coming up regularly.

Brand new mac studio, clean OS install, new photoshop install, same error. Only now I get it like 3 times in a row. Adobe, please stop giving me useless Ai functionality and just give a stable photoshop.

Corporate enshittification.
Adobe is on the backend of relevance.
Theyre just pumping the stock now.
Its 5 years later and they havent even addressed the issue, much less fixed it.
And they never will.
