I would recommend starting over with a fresh install of the Raspberry Pi OS (Buster) before installing Build a Pi (BAP). Currently you have a half installed system.
It only appeared stuck during the FLDIGI build. It takes a lot of patience when building FLDIGI on a Pi 3. It is one of the longest sections during the build.
After you have a successful build, you will be able to start the vast majority of applications from teh Pi menu.
