Yamaha USB Driver

Is there any tip to follow when after installing the driver, few times, this sill is not detected?
The icon is visible in the system setting window, but once clickin on it only a system error sound is played and nothing happen.

I’m using a iMac 2019 with catalina 10.15.7
input an Arturia key step 37, well detected, with a VCV rack which is NOT see the UR22 mkII.

any tips are well accepted, thanks in advance from a beginner
