Since the last update, my K95 Platinum will also randomly hard freeze, icue will stop and I have to cold reboot because I'm in a game where I can't get out without the keyboard or Cntrl-Alt-Delete. Typing this now on an old Logitech keyboard that just works whenever I plug it in without software. I've got void pro rgb, dark core se, k95 platinum, st100 headphone stand, corsair case and memory. This is new behavior. I have to climb under my desk, unplug the dual keyboard plugs, reboot, plug back in and hope it works. Has taken a couple of times to be recognized. Like OP, not sure if K95 is going bad or it's an iCue problem, but it always happens in the middle of a game. My k95 about 6 months old. Anyone got any troubleshooting help? Not sure how to troubleshoot a keyboard, as I've never had a problem with one before.
