Bootstrap dropdown-toggle doesn't toggle

I'm at my wits end. I started up a new ASP.Net core web app and am trying to add a simple menu with a dropdown. However, the dropdown won't toggle open.

(And when is stackoverflow going to remove the ridiculous "issue" of you need more content to match the amount of code you're posting. Sometimes a question is short! Thanks!)

The dropdown:

                        <li class="nav-item dropdown">
                        <a class="nav-link text-dark dropdown-toggle" data-toggle="dropdown" asp-area="">Json</a>
                        <span class="caret"></span></a>
                        <ul class="dropdown-menu">
                            <li><a class="nav-link text-dark" asp-area="" asp-page="LoadJson">Load Json</a></li>
                            <li><a class="nav-link text-dark" asp-area="" asp-page="BulkLoadJson">Bulk Load Json</a></li>
                        </ul>
                    </li>

All the code in the page:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>@ViewData["Title"] - DataMagnifierAdmin</title>
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />
    <link rel="stylesheet" href="~/css/site.css" asp-append-version="true" />
    <link rel="stylesheet" href="~/DataMagnifier_Admin.styles.css" asp-append-version="true" />
</head>
<body>

Change data-toggle="dropdown" (Bootstrap 4) to data-bs-toggle="dropdown" (Bootstrap 5).

See the snippet below.

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-rbsA2VBKQhggwzxH7pPCaAqO46MgnOM80zW1RWuH61DGLwZJEdK2Kadq2F9CUG65" crossorigin="anonymous">
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-kenU1KFdBIe4zVF0s0G1M5b4hcpxyD9F7jL+jjXkk+Q2h455rYXK/7HAuoJl+0I4" crossorigin="anonymous"></script>

<li class="nav-item dropdown">
  <a class="nav-link text-dark dropdown-toggle" data-bs-toggle="dropdown" asp-area="">Json</a>
  <span class="caret"></span>
  <ul class="dropdown-menu">
    <li><a class="nav-link text-dark" asp-area="" asp-page="LoadJson">Load Json</a></li>
    <li><a class="nav-link text-dark" asp-area="" asp-page="BulkLoadJson">Bulk Load Json</a></li>
  </ul>
</li>
