Rekordbox crashing when importing iTunes playlist

Recently purchased DDJ-1000 and Rekordbox.

Have always managed my music via iTunes

Imported playlists first time (crashed a couple of times, but we got there)

Deleted playlists, and then re-added them (to see if changes I made in iTunes would reflect in Rekordbox, they don’t, annoyingly - will post separately on this issue)

However, now when trying to re-import the playlists, the computer crashes every time stalling on “Importing 10406/10422”, which would be about the same number of new tracks I’ve added to my iTunes playlist that I’m trying to re-import.

I’m running windows/latest Rekordbox version etc
