UR22C driver 2.0.4 doesn’t work

Hello, I’m having the same problem with the Yamaha UR22C Driver for my audio interface. I followed the steps to fix the problem but it didn’t work at all. My Mac has the latest software version (BigSur 11.1). I’m really worried because I can’t do my job. What a shame, I should’ve bought the Focusrite. Big problem.
