Kontakt/Komplete Kontrol - Black Box inside Logic Pro 11

Exactly as the title states, a Black Box appears when trying to load instruments into either Komplete Kontrol or Kontakt (7 and 8 player). The box is the same size as the loading popup screen and it appears once the instrument finishes loading. It's as though the loading screen just turns into this Black Box and once it appears I can no longer remove KK/Kontakt from the instrument, nor can I create any new instruments. The keyboard shortcuts also stop working. Basically I'm forced to quit Logic but Quit is also unavailable so I'm forced to "force quit" Logic which isn't great.

I've posted about this here before and didn't receive any replies but I'm trying again out of desperation. I've been on NI and Apple Support Calls for the last month and a half or so trying to pin point the source of this issue.

After two weeks or so of troubleshooting with NI, they said, "Well, it's only happening in Logic and not in Ableton or in the standalone app so you need to contact Apple."

Apple did very little troubleshooting on their end and basically just told me to setup a new admin user in Mac OS and then via some fancy terminal commands allowed me to access previous user info to copy over what I needed.

Anyway, that is a very short summary of what has been a very long and hair pulling process.

And despite all that, just this morning…it happened again on the new user account. I ordered a new Mac Studio last week and if I don't get this fixed by Sunday when it arrives my plan is to forego Mac Migration Assistant and create a completely new user, installing only the necessary software, one item at a time and testing every step of the way until I've found the culprit. Embarrassingly, I have a lot of plugins on my system (maybe 300? 😬) so this is bound to be a long and arduous process. There's probably some old software or preference file in there somewhere that's clogging up the system. Hard to know what it is.

Also I have a KK S88 MK3 but the issue is happening even when the keyboard is unplugged from the Mac so that is unlikely the issue?

Anyway, please have a look at the video if you have time and if you have any suggestions as to what it might be I'm all ears. Appreciated
