It sounds like you have two applications fighting over the same driver. What I would do, which I think would fix this pretty quickly, is to uninstall the associated software, restart, then re-install the software.
Another option would be to look through the plugins/add-ons in the browser that you are using, to see if there is a second agent in the browser that is causing the problem. You didn't mention your scanner make or model, so I know this information isn't very specific, but it's the best I can provide for right now.
I would be curious to find out, at least for troubleshooting, if you have the same problem with a different browser - for example, if you are using Internet Explorer, whether it would work properly if you tried using it with Chrome. That would rule in or out whether it is something in the browser causing it.
I checked the specs for this scanner - Canon doesn't offer a Windows 10 driver - the highest compatibility they offer is Windows 8.1. I don't know the specs of your new computer, but that might be something to consider. I can submit an additional services ticket for remote desktop support for you to approve.
