Recordin with built-in microphone

I am trying to use, for testing purposes, the built-in microphone of an Apple Studio Display connected to a Mac Studio with Cubase.

After creating a mono track, in the Audio Connections section, under Audio Device, when I try to select “Built-in Audio”, Cubase does not retain the selection.

I also tried to force the microphone access request using the command:

tccutil reset Microphone

but nothing changes. When I reopen Cubase, under Privacy & Security there is still no microphone access request from Cubase.

Could anyone suggest a solution?
