I have a DELL 15 3000 laptop with ryzen i5 2ghz 32gb RAM and Traktor crashes with both versions of Native Instruments (3.8 and 3.9)
With the 3.8 version, the music slows down (on its own) and is very laggy for a few seconds and then goes back to normal.
With the 3.9 version, the music stops (on its own) and then comes back.
