Extremely slow Playlist transfer from Rekordbox to USB

Hi everyone,

i just got a brand new sandisk extreme go usb but rekordbox takes ages to import around 1800 tracks to usb. I m pretty sure it shouldnt take more than a few minutes, but rekordbox takes hours to export (maybe 3 or 4% per hour). Im sure this should be done in less than 10 minutes. also while exporting, rekordbox isnt really reacting to any input, when i click at something with my mouse, i just get the spinning wheel. CPU usage is at about 10-15%, no other programs r running. i m using an m1 macbook air with the latest rekordbox update (6.6.8)
