UR22C-Ventura M2: dspMixFx (2)- No device found

This topic has been discussed but does not seem pertinent to Ventura OS on M2.
I have followed all instructions including the new process of allowing a developer add to the system. The dspMixF is in my applications and the Yamaha driver is operating. The application is in the Audio Midi utility. But still Ventura returns: "No Device Found.

If this is a no go. I think I can uninstall the tools and the driver and the UR22C should work as Class Compliant. Pity if this is to be.
Any help would be appreciated.

I am happy to go through the whole install process again
