Rekordbox continuous freezing issues

Rekordbox continually freezes.

Computer : Dell G7. I7-8750 H CPU @ 2.20 GHz. 16GB Ram. 64 bit, Windows 10

Mixer : DJM-450

CDJ : 2 XDJ-1000MK2's

Mixer and both xdjs are connected to a usb hub that is connected to laptop.

While using Rekodbox, it just continually freezes on me and I have to restart the program. Within a 2 hour session, this usually happens like 5 times.

Only other programs running besides rekordbox is windows sticky notes, and chrome browser. No videos running or anything.

Why do i keep encountering these issues with rekordbox freezing?

I believe I have beyond enough computer power to run this program.
