MacOS Mojave + Rekordbox 5.6.1

I just got a new laptop and every time I download Rekordbox and it's installed, when I try opening the app, it'll give me a  "rekordbox quit unexpectedly" message. After researching the issue, I found that I need to grant Rekordbox access to the mic/audio but I'm not given that option. The box doesn't appear during the downloading process. See below for screen shots:

Can anyone help? I have a gig on Sat. so I need to figure this out ASAP.
