I have this exact same problem for the IJ Scan utility using my MG5520. I've downloaded all of the latest print & scan drivers and the latest scan utility ... and applied all of the latest MacOS updates for MacOS Catalina 10.15.1.

I have the same problem with a Lide220 Scanner and this worked so it may work for you.
