Printer - Pixma Pro 100. Print Studio Pro V2.2.5 installed. Lightroom V12.01. Everything worked fine with macOS 12 Monterey. Just upgraded to macOS 13 Ventura and I now get the following error message when I select a photo in Lightroom and run the plugin for Print Studio Pro (and Print Studio Pro opens) : AN ERROR HAS OCCURRED. EXITING PRINT STUDIO PRO. An exhaustive search of the internet yielded no results. Anyone else having this problem? Many thanks for any help.
