Bootstrap Barrio theme assume that the theme is handling the main menu rendering.
Toi avoid conflicts with the theme modify on your subtheme the main navigation markup of your page.html.twig removing all responsive menu rendering markup from line 84, to endup with this simpe code:

{% if page.primary_menu or page.header_form %}
   {{ page.primary_menu }}
   {% if page.header_form %}
       <div class="form-inline navbar-form justify-content-end">
          {{ page.header_form }}
       </div>
    {% endif %}
{% endif %}
