dialog box when closing PS

[defaultjkpq0eqasuph]

Hi,

I'm running PS 2021 and Lightroom Classic, latest updates, on a Mac with OS 10.14.6. My normal workflow from within LR involves using Edit In > Photoshop for some images. I do my PS work and save the file back to LR. Everything works as expected except I get the dialog box (shown in attachment) saying PS could not export the clipboard because it is too big. AFAIK, I'm not trying to export the clipboard nor do I want to. What is the message for and how can I get it to stop appearing?

Thank you,

Dan

I've never seen such a error message.

Please reset the Photoshop preferences to the default settings and try again.

You can set your Photoshop Preferences not to export to the clipboard.

Thanks, JJMack!

Of course, I'm looking for a more complex reason + solution. Never would have thought about preferences.

Have a great weekend.
