Canon IJ Scan Utility Light not connecting to scanner after MacBook Pro macOS Tahoe upgrade

I have upgraded my MacBook Pro to Tahoe, currently on 26.1.

My Canon G600 connects with AirPrint on the LAN and works normally. However Canon IJ Scan Utility Light v4.2.0 does not find the Scanner since the upgrade showing the 'Cannot connect with Scanner' message.

It works normally on my wife's MacBook Air running Sequoia v 15.7.1

I have restarted both computer and printer, reinstalled IJ Scan Utility Light but with no success

Does the IJ Scan Utility light not support Tahoe?

Does the Apple Image Capture app work with the scanner?

Is the firmware current? https://ij.manual.canon/ij/webmanual/Manual/All/G600%20series/EN/UG/ug-178.html

Yes the firmware is up to date.

The G600 Printer/scanner is the default printer on System Settings but does not show on Apple Image Capture. I assume this is because it is connected via the LAN, not by cable??

Printer sharing is selected.
