How do I change the code for breadcrumbs in the master theme?

[Valeria_16]

what to do if a link redirect is made

and because of this, the breadcrumbs do not work correctly, they do not display the desired collection.

this is the code that is currently used for bread crumbs. but due to the fact that the name of the collection is not displayed in the link, the collection is not displayed.

{% assign search_category = search_category | default: blank %}
{% assign show_breadcrumbs = true %}

{% if show_breadcrumbs %}
{% capture cat_array %}{%- render 'advanced-tag-loop' -%}{% endcapture %}
{% assign cat_array = cat_array | split: '|' %}

{%- capture delimiter -%}
<span class="breadcrumbs-delimiter" aria-hidden="true">
{% render 'icon-chevron-down-thin' %}
</span>
{%- endcapture -%}

<nav
class="breadcrumbs-container"
aria-label="{{ 'general.accessibility.nav_breadcrumbs' | t }}"
>
<a href="{{ routes.root_url }}">{{ 'general.breadcrumbs.home' | t }}</a>
{% if template contains 'page' %}

{{ delimiter }}
<span>{{ page.title }}</span>

{% elsif template contains 'product' %}

{% if collection.url %}
{{ delimiter }}
{{ collection.title | link_to: collection.url }}
{% endif %}
{{ delimiter }}
<span>{{ product.title }}</span>

{% elsif template contains 'list-collections' %}

{{ delimiter }}
<span>{{ 'general.breadcrumbs.collections' | t }}</span>

{% elsif template contains 'collection' and collection.handle %}

{{ delimiter }}
{% if current_tags %}
{% capture url %}{{ routes.collections_url }}/{{ collection.handle }}{% endcapture %}
{{ collection.title | link_to: url }}
{{ delimiter }}

{% for tag in current_tags %}

{% assign is_advanced_tag = false %}
{% assign cat = tag | split: '_' | first %}
{% unless cat == tag %}
{% if cat_array contains cat %}
{% assign is_advanced_tag = true %}
<span class="breadcrumbs-tag">
{{ tag | remove_first: cat | remove_first: '_' }}
</span>
{% endif %}
{% endunless %}

{% unless is_advanced_tag %}
<span class="breadcrumbs-tag">{{ tag }}</span>
{% endunless %}

{% unless forloop.last %}
<span class="breadcrumbs-tag">+</span>
{% endunless %}
{% endfor %}
{% else %}
<span>{{ collection.title }}</span>
{% endif %}

{% elsif template == 'blog' %}

{{ delimiter }}
{% if current_tags %}
{{ blog.title | link_to: blog.url }}
{{ delimiter }}
<span>{{ current_tags | join: " + " }}</span>
{% else %}
<span>{{ blog.title }}</span>
{% endif %}

{% elsif template == 'article' %}

{{ delimiter }}
{{ blog.title | link_to: blog.url }}
{{ delimiter }}
<span>{{ article.title }}</span>

{% elsif template contains 'search' and search.performed %}
{% capture sanitized_terms %}
{%
render 'search-sanitizer',
search_terms: search.terms
%}
{% endcapture %}

{% assign sanitized_terms = sanitized_terms | strip %}

{{ delimiter }}

{% if search_category != blank %}
<span>
{{

| t: terms: sanitized_terms, category: search_category, count: search.results_count
}}
</span>
{% else %}
<span>{{ 'search.general.breadcrumbs_count' | t: terms: sanitized_terms, count: search.results_count, results: results }}</span>
{% endif %}

{% else %}
