Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
Under GNURadio companion (Debian 12), I want to use the "RFNoC Graph (Device)" block.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Drag the "RFNoc Graph (Device)" menu entry and drop it on the flowgraph window.
   * What was the outcome of this action?
The block does not appear in the flowgraph window.
The following error messages are printed in the terminal:
