UR22 + 3.0.5 driver not working on Big Sur

Hi, I have a MacBook Air 2013 which just updated to Big Sur. I installed the 3.0.5 driver, but my UR22 isn’t working - white flashing LED.

I’ve called local (AU) support and got an answering machine, so left a message.

I’m in the middle of recording a new album and am 100% stuck. Can anyone please help?

Thanks,
Zac
