MK3 S88 and Cubase 12 Pro connectivity issue

JGlibbery

I just purchased a Native Instruments MK3 88 controller and I am having a real tough time getting it to work in Cubase. I have gone through all installation procedures from NI through the Native Access, Komplete Kontrol. The keyboard is registered properly.  
Things seem to be unstable as a couple of times I have been able to get it be "seen" by Cubase and have it actually send MIDI data to the program and into a VST but only a couple of times. The rest are all basically a frozen start up screen from Cubase when doing its scan etc. It seems to hang up on a "Mackie Control" prompt on the screen and then sits there for eternity. I actually power down the MK3 and Cubase immediately continues onto booting up but is frozen and I have to shut it down via Task Manager. See attached PNG . I am at a loss here. Is this a Cubase issue? Is my computer rig not powerful enough? I have contacted support via Native Instruments but but my problem is not resolved. Up to now, Cubase 12 PRO has worked well for me with no issues.   Im attaching my Windows 10 system details as well.  Any ideas?

  Thanks!

@JGlibbery Before setting it up for Cubase, it's always a good practice to check if everything is working normally in Komplete Kontrol in standalone. Can you browse, load, play and control a preset there? If not, please follow these steps: My Komplete Kontrol Keyboard Does Not Start

Mackie Control should not be an issue with the MK3 keyboard, it doesn't use the MCU protocol. Do you have more controllers on your system?
