Custom WordPress Theme loads js but not stylesheets

I have looked around as best I could, but I could not find a solution to this problem. I am building a custom WordPress template from scratch and the stylesheets won’t load. For some reason, the javascript does. Here is what I have:

The enqueue in functions.php

<?php  function test_enqueue_styles(){     wp_enqueue_style('test-style', get_template_directory_uri() . "/style.css", array('test-bootstrap-css'), wp_get_theme()->get( 'Version' ));     wp_enqueue_style('test-bootstrap-css', get_template_directory_uri() . "/assets/css/bootstrap.css", array(), '5.1.2');     wp_enqueue_style('test-icons', "https://cdn.jsdelivr.net/npm/bootstrap-icons@1.4.1/font/bootstrap-icons.css", array(), '1.4.1');  } add_action( 'wp_enqueue_style', 'test_enqueue_styles');  function test_enqueue_scripts(){     wp_enqueue_script('test-bootstrap-js', get_template_directory_uri() . "/assets/js/scripts.js", array(), wp_get_theme()->get( 'Version' ));     wp_enqueue_script('test-bootstrap-js', get_template_directory_uri() . "/assets/js/bootstrap.js", array(), '5.1.2');     wp_enqueue_script('test-bootstrap-bundle', "https://cdn.jsdelivr.net/npm/bootstrap@5.1.1/dist/js/bootstrap.bundle.min.js", array(), '5.1.1');      } add_action( 'wp_enqueue_scripts', 'test_enqueue_scripts');  ?> 

my testing style in style.css:

/* Theme Name: Test Theme Theme Domain: Test Theme Version: 1.0 Description: A test theme for WordPress Author: Me */  body{     background-color: crimson !important; } 

the only page with content is front-page.php:

<!DOCTYPE html> <html lang="en">     <head>         <meta charset="utf-8" />         <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />         <title>Hello World</title>         <link rel="icon" type="image/x-icon" href="assets/favicon.ico" />         <!-- Stylesheets-->         <?php             wp_head();         ?>  <!--NOTE THESE COMMENTED LINES-->         <!-- <link href="https://cdn.jsdelivr.net/npm/bootstrap-icons@1.4.1/font/bootstrap-icons.css" rel="stylesheet" />         <link href="wp-content/themes/testtheme/assets/css/bootstrap.css" rel="stylesheet" />         <link href="wp-content/themes/testtheme/style.css" rel="stylesheet" /> -->     </head>     <body>         <div class="container">             <h1 class="jumbotron">Hello World</h1>         </div>          <?php        wp_footer();             ?>     </body> </html> 

When I uncomment the lines mentioned in front-page.php, The page works excactly as intended. Otherwise, the three stylesheets do not load from wp_head(). Period. They don’t appear on the page source and are not referenced in the developer tools network tab regardless of how many times I hit ctrl+f5.

Strangely enough, the script enqueue from the same file loads the scripts. The scripts show up in the network tab and a console log in scripts.js outputs to the console. It’s just the stylesheets that bug out. Bootstrap is v5.1.2, downloaded directly from getbootstrap.com

I have also tried the following for functions.php:

<?php  function test_enqueue_styles(){     wp_register_style('test-style', get_template_directory_uri() . "/style.css", array('test-bootstrap'), wp_get_theme()->get( 'Version' ));     wp_register_style('test-bootstrap', get_template_directory_uri() . "/assets/css/style.css", array(), '1.0');     wp_register_style('test-icons', "https://cdn.jsdelivr.net/npm/bootstrap-icons@1.4.1/font/bootstrap-icons.css", array(), '1.0');      wp_enqueue_style('test-style');     wp_enqueue_style('test-bootstrap');     wp_enqueue_style('test-icons'); } add_action( 'wp_enqueue_style', 'test_enqueue_styles');  //javascript same as above ?> 

Nothing seems to work! Is there something I am missing?

I am running WordPress Version 5.8.1 if that matters.
