Lightroom Classic 12.3 freezes on MacOS 12.6.5 when exporting

[Mark29943800ahv0]

I have updated to the latest version of MacOS Monterey and the latest version of Lightroom Classic. I can import, tag, process photos in my library fine. However, when I try to export files from the Quick Collection I have issues. I choose to export format JPEG. I can change quality settings, sharpening etc, but when I choose to resize by Long Edge as soon as I click in the box to change the number of pixels I get the spinning wheel and the app no longer responds and has to be Force Quit. This happens whether GPU is enabled in performance or not.
