I also uninstalled KB4560960 update and paused updates. My Brother printer is able to work again, BUT now during any use of the printer or its scanner, the computer freezes repeatedly. In any 5 second interval, the computer might respond for a half second.
When the printer/scanner is not being used, the computer will often not respond randomly for perhaps one to three seconds every 15-20 seconds. If the printer is turned off, there are still random short freeze-ups. If I unplug the printer USB from the computer,
the freeze-ups stop.
I faced the same problem when my printer was not printing up my 90s Anime poster. I uninstalled the update then restarted. The problem seemed to have been solved.
