Three separate failures, all Windows-only: The world path went into a PythonExpression string literal, where a Windows path is read as escapes. It crashed on the drive-relative part, and a folder whose name starts with n would have silently become a newline. Pass it as a posix path; Gazebo accepts forward slashes everywhere. gz sim then refused to run: the server and the Qt GUI cannot share a process on Windows any more than on macOS (gz-sim#168). Windows now takes the same split macOS already used, running the server with -s and the GUI separately. That GUI process could not start either: gz is a .bat on Windows and ExecuteProcess does not search PATHEXT, so it exited with WinError 2. Resolve the path before handing it over.
…dows base_path is pasted straight into a file:// URI in inmoov.urdf.xacro. With Windows backslashes that produced file://C:\...\description/robot_description/..., which gz could not resolve, so every visual failed to load and the robot appeared in the window with no geometry.

Mesh URIs and the Gazebo GUI break on Windows.
base_pathis pasted intofile://$(arg base_path)/robot_description/meshes/dae; with backslashes gz cannot resolve it, so the robot renders with no geometry.gzis a.baton Windows, andExecuteProcessdoes not searchPATHEXT, so the GUI process was never found — resolve it withshutil.which.Verified locally: the InMoov renders in the Gazebo window on Windows with these applied.
