If structure set is attempted to be loaded by Scalar Volume plugin (as the error message suggests) then it means SlicerRT did not recognize the series - most likely it was not installed (or the installation was incorrect/incomplete).

Try to uninstall SlicerRT and install it again (wait until the “Restart” button becomes enabled in Extension manager, don’t close the window and restart the button manually).

If that fails then follow further instructions in the DICOM FAQ as Steve suggested above.
