I had this issue a couple of times now, and could not figure out how I worked it out the first time. This second time (after an update I believe) I had the same issue. I looked for a fix, but could not get a clear answer.
It seems it "FIXED" the issue By Launching Native Access, and Reinstalling "Komplete Kontrol."
This Fixed the Issue.. I just thought to share this here as an OPTION to Try, for a Possible Solution — just looking out!
Best 😁
