This started to happen after Apple updated MACs for security reasons. I re-installed the PPL software, resigned all my printers back in to no avail. PPL will print standalone and I can print from Photoshop but Photoshop refuses to pass an image on to PPL.

Seems that this is a known issue due to Apple's security update version 11.6 Big Sur. When PPL is started from PS, the image is not passed for printing and it locks up PS resulting in a force quit. Work around is to either print using the PS print engine or use PPL stand alone which works nicely for JPEG and TIFF files. Canon is working on the problem. Typical software update on Apples's part: fix one thing, break many others.
PPL does work well in stand alone. It actually works better when integrated into your workflow. I am a professional printer and can speak for Canon as with my last conversation with them, they said a fix is in the works. Use PPL stand alone for now and give it time. I think you'll like working with PPL better this way as this application is a memory hog but when used separately, you may go from Bridge and PS with ease. Let me know you thoughts as integration with PS may not be as important as you think.

I have the same issue but with a twist. When I use Professional Print and Layout (PPL) as a stand alone application, it will only open the image file when I drag and drop, not when I initiate from the Open menu choice. I am running a new McBook Pro M1 on Monterey. I’m guessing the problem is due to security blocking but I have opened up permission for the program.
