Need help with slideshow banner code editing on Venture 8.1?

[system]

I’m fixing our company website currently using Venture 8.1 and I have a bug that appears when I resize the window on desktop devices. I have the website looking like this:

When you minimize it and resize the window then maximize again, then it looks like this, and the only way to fix it is to refresh the page:

I don’t want more than 1 image in this slideshow. When the window is resized, I’d like to make it so the slideshow doesn’t try to navigate to the 2nd slide. Any ideas on how I can fix this issue? Also, is it possible to add a video somehow instead of just images on this theme?

Here is the code to slideshow.liquid:

{% if section.blocks.size > 0 %}
  
    
    

      {% for block in section.blocks %}
        

          

            {% if block.settings.image != blank %}
              
              {% assign img_url = block.settings.image | img_url: '1x1' | replace: '_1x1.', '_{width}x.' %}
              
            {% else %}
              {% if block.settings.image == blank %}
                
                  {{ 'lifestyle-1' | placeholder_svg_tag: 'placeholder-svg' }}
                

              {% endif %}
            {% endif %}
            
              

                

                  {% unless block.settings.title == blank %}
                    

                      # 
                        {{ block.settings.title | escape }}
                      
                    

                  {% endunless %}

                  {% if section.blocks.size > 1 %}
                    
                      
                        {% include 'icon-arrow-left' %}
                        {{ 'homepage.hero.previous_slide' | t }}
                      
                      
                        {% include 'icon-arrow-right' %}
                        {{ 'homepage.hero.next_slide' | t }}
                      
                    

                  {% endif %}

                  {% unless block.settings.subheading == blank %}
                      
                        {{ block.settings.subheading | escape }}
                      
                  {% endunless %}
                  
                  {% unless block.settings.button == blank %}

                    {% else %}
                      
                        {{ block.settings.button | escape }}
                      
                    {% endif %}
                  

                  {% endunless %}
