   In the 3D Viewport press N and choose the xxerb B2U Link tab.

   In Unreal Bridge, press Refresh Instances and choose the detected project.

Make a safe first test

Use a small test project and a simple cube first. Save the .blend file in its own folder so the generated Content source directory and placement file are easy to inspect.
