Rekordbox not fully opening on my Macbook pro (late 2013)

Hi

Long time user 1st time loser.

Any help would greatly be appreciated.

I am running a Mackbook Pro (Retina, 15-inch, Late 2013) w/ mac0s Big Sur version 11.7.10

I open Rekordbox (6.7.1), it shows the software is opening with the rekordbox box at the top of the screen, the loading tracks bit dosent load the tracks from 0%, then I am left with the program showing its open at the top of the screen but cant see the software, then I have to force quit to close.

I then try and open an older version like 5.8.1 and it shows that it reads the tracks to 100% then have the same issue as above.

Again any help would be greatly appreciated.
