Using an django-sass-processor library in django but refuses to apply the style because its MIME type is not a supported stylesheet

Question

I'm using Sass for my Django(3.2.6) website with the help of libraries called django-compressor and django-sass-processor to compile it to a .css file. It works fine during development but when I try to disable the DEBUG mode in the settings the error will pop-up.

Refused to apply style from 'http://127.0.0.1:8000/static/styles.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Setting up the library I've added the following code to my settings.py (between ---- lines):

Here are my static directory files structure BEFORE running library:

    .
├── public (folder for images)
├── _scss (folder for .scss files)
└── styles.scss

AFTER running library, it created two files called styles.css.map and styles.css:

.
├── public 
├── _scss 
├── styles.css
├── styles.css.map
└── styles.scss

To access scss tags, HTML now use {% load scss_tags %} tag, here is my head.html:

{% load sass_tags %}
<head>
  <meta charset="UTF-8">
  <link href="http://gmpg.org/xfn/11" rel="profile">
  <link type="text/plain" rel="author" href="{% url 'index' %}/humans.txt">

  <!-- Enable responsiveness on mobile devices-->
  <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1">

  <meta property="og:title" content="{{ site_title }}">
  <meta property="og:site_name" content="{{ site_brand_name }}">
  <meta property="og:url" content="{% url 'index'} %">
  <meta property="og:description" content="{{ site_description }}">
  <meta property="og:type" content="website">
  <meta property="og:image" content="{% sass_src 'public/meta-img.png' %}">

  <link rel="stylesheet" href="https://unicons.iconscout.com/release/v2.0.1/css/unicons.css">

  <title>
      {% block title %}
            Open Siena Files
      {% endblock title %}
  </title>

  <!-- CSS -->
  <link type="text/css" rel="stylesheet" href="{% sass_src 'styles.scss' %}" >

  <!-- Icons -->
  <link rel="shortcut icon" href="{% sass_src 'public/favicon.ico' %}">
</head>

But when running it without DEBUG mode the browser produces the error. YES YES YES. I already search for a solution but nothing seems to fit with specific problem I have about library converting scss to css.
