Why isn't my Bootstrap dropdown displaying any options?

I am new to web development and attempting to create a button that triggers a dropdown menu when clicked. I have tried the following code, but for some reason, the dropdown is not working correctly. Can anyone help me identify the issue or correct my code? Thank you very much.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <link rel="stylesheet" href="css/bootstrap.css" />
  </head>
  <body>
    <div class="row m-2">
      <div class="col"><h2>Logo</h2></div>
      <div class="col">
        <div class="dropdown">
          <div
            class="btn btn-success dropdown-toggle"
            id="x"
            data-toggle="dropdown"
          >
            Courses
          </div>
          <div class="dropdown-menu" aria-labelledby="x">
            <a href="#" class="dropdown-item">A1</a>
            <a href="#" class="dropdown-item">A2</a>
            <a href="#" class="dropdown-item">B1</a>
            <a href="#" class="dropdown-item">B2</a>
          </div>
        </div>
      </div>
      <div class="col"><div class="btn btn-outline-dark">About me</div></div>
      <div class="col"><div class="btn btn-outline-dark">Contact</div></div>
    </div>

    <script src="js/popper.min.js"></script>
    <script src="js/jquery-3.7.1.min.js"></script>
    <script src="js/bootstrap.js"></script>
  </body>
</html>

Currently experimenting with creating a navigation bar with buttons that trigger dropdown menus upon clicking.

Your code seems to be functioning properly, ensure you have the correct version of popper library installed.

Here is a functional demonstration using popperjs version 1.16.1 without any changes in HTML:
