Rekordbox crashes when selecting PAD or MIDI

Hello all,

I've just installed Big Sur on the back of a recent communication advising it's now compatible with Rekordbox products. I decided to go with a completely fresh Mac install and start from scratch (with a backup/restore of my library).

Everything runs fine except for when I try to edit the pads or midi settings while the DDJ1000 is plugged in. Clicking either icon crashes the software entirely.

I'm used to playing with a customised re-mapped setup and this will be a massive headache if I can't now remap them.

Please help!
