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?
