I ran through this checklist here and am still stuck:
When Kontakt 8 is looking for libraries they fail to load and show the resulting screenshot. Attempting to resolve automatically or resolve manually does not work. Once you press open the screen goes away and goes back to the Kontakt 8 library.
Native Access does not show any broken libraries. I have tried deleting the database and Kontakt 8 and even reinstalled Kontakt entirely. This issue also occurs in Komplete Kontrol.
I am on a mac.
This was working without issue until today. Nothing changed between the time it worked and today. Suddenly it was just broken. Kontakt loads in Logic Pro X but the libraries do not.
My frustrations are shared by the author of the above post. After paying thousands of dollars for libraries why can't they just work..
