Answer 1

You do not have (an installed) INET project in your workspace, or the INET project is not open or it is not set as a project dependency in Simu5G's project properties dialog.

Answer 2

I have experienced the similar issue in SimuLTE. This is due to an invalid project reference setting. To fix it: Right Click the projet - Property - Project Reference, then select the inet you installed.
