There is a possibility that Blizzard accidentally put a corrupt or broken FMOD.dll (and FMOD64.dll) into the game install with the latest patch. There are numerous players experiencing crashing with the FMOD system. As a last resort you could try removing the problematic FMOD file and trying the workaround found here and then following up with creating a shortcut for Diablo 3 that will let you launch the game without the Battle.net app replacing the modified FMOD file with the broken one.
Edit: I would keep iCue uninstalled until Corsair fixes it though. It’s obviously a part of your problem as it was identified as a prime component in your dxdiag report. Keeping it out of the equation as a rogue variable is strongly recommended.
