Minilogue Sound Library no longer connecting through midi

[LittleMo]

I have recently updated my Mac to Big Sur 11.2.1 - now my Minilogue Sound Library is no longer connecting to my Minilogue displaying the "minilogue is not connected" error message.

The Minilogue icon in my Audio MIDI setup has a red question mark. I have tried resetting the devices through Audio MIDI setup but it still comes up with a question mark.

I have unistalled the Korg drivers so it's not that.

Any ideas on how I can get the sound library to work again?

Thanks
