Rekordbox DJ v.4.2.4 w. DDJ-RZ crashes

Hi,

I've setup a dedicated laptop for Rekordbox DJ, but continue to experience crashes, both on 4.2.2 and 4.2.4.

The crashes start with the GUI freezing, but music playing underneath. The second I hit a button on the controller, the application crashes and exits immediately after. 

System specs can be found in the DxDiag.txt file below.

This is quite frankly getting VERY annoying. Hours of work ruined.
