Custom Theme CSS Stopped Working

I’m trying to create a custom theme and everything was going as suspected until now. I’m using MAMP for my local environment and so far I only have the index, header, footer, functions and css files.

My initial styling worked fine but now I can’t make changes. It strange because I can comment out all of the styling and nothing changes, but if I comment out the wp_enqueue_style function I do lose the styling. It’s like I’m stuck with the styling I did up to this point.

This all starting happening after adding my custom logo.

here is my functions.php file

<?php

// ADD CUSTOM STYLESHEETS
function custom_theme_assets() {
  wp_enqueue_style('style', get_stylesheet_uri());
}
add_action('wp_enqueue_scripts', 'custom_theme_assets');

// REGISTER PRIMARY MENU
register_nav_menus(['primary' => __('Primary Menu')]);

// Add CUSTOM LOGO
function custom_logo_setup() {
 $defaults = array(
 'height'      => 100,
 'width'       => 400,
 'flex-height' => true,
 'flex-width'  => true,
 'header-text' => array( 'site-title', 'site-description' ),
 );
 add_theme_support( 'custom-logo', $defaults );
}
add_action( 'after_setup_theme', 'custom_logo_setup' );

Here is the code for adding the logo in my header file

<?php 
   // maintain backward compatibility with the older versions of WordPress
   if ( function_exists( 'the_custom_logo' ) ) {
     the_custom_logo();
   }
?>

I only give you this because the problem started after I worked on the logo. I tried removing this code but nothing changed.
