Grove Shield for Arduino Nano v1.0 can it be used with a Nano RP2040

Hi, I bought a grove shield for Arduino Nano v1.0. I wanted to use it with a Arduino Nano Connect RP2040.
I experienced that when I mount the Arduino Nano Connect to the shield, the Nano is losing the ability to create a USB serial port. When I take the Nano Connect RP2040 off the grove shield the Nano is again able to establish a USB serial connection with a host PC.

Yet it is eight days ago that I created my post. No reaction at all! Why?
