Canon Professional Print and Layout won't launch from Lightroom

[Vendee]

A couple of months ago I bought a Canon PRO300 printer which I absolutely love. I also chose to use the Canon Professional Print and Layout software for making the prints. I think its a great piece of software which gets great results for me. I would edit my image in Photoshop and then launch the Canon PPL software from there using the installed plugin. It worked flawlessly.

Recently however I became converted to using Lightroom to edit my images but I can't launch the Canon PPL from Lightroom. The plugin is installed but when I launch PPL, I get a status message stating "Opening Canon Professional Print & Layout" but the message disappears after a few seconds and PPL does not load.

Any ideas?  Thanks.

Windows 10. Lightroom 12.1 Canon PPL 1.3.6

Have you tried removing it then reinstalling it?

I've removed and reinstalled the Canon PPL software and the plugins. I've not touched Lightroom. I get round it by moving the image from LR to PS then using PS to transfer the image to Canon PPL. I'll wait until the next version of LR is released and see if that fixes the issue. Of course I don't know if the problem lies with LR or Canon. Thanks.
