I started getting this behavior after I reset the Application location in Native Access (which was showing me an error, so I followed steps to fix it).
It flashes this window briefly almost as a stutter, glitch effect then opens the main window. Kontakt still runs fine once it's open, but it's a bit jarring and I'm hoping to fix this. I tried reinstalling Kontakt but no luck.
The behavior doesn't happen when I run Logic with Rosetta, however I prefer not to run it with Rosetta.
I'm using a Mac Studio Ultra, Logic 10.7.5, Ventura, Kontakt 7.0
