Null reference in freshly created asp.net web application

I have successfully created asp.net web applications in the past, but I have never encountered this issue before. I just created a new project. I enabled migrations and I updated the database, but there is no changes that I have made to the code. Yet, when I navigate to the default login page, I get null reference exceptions for all of the Html.TextBoxFor methods such as @Html.TextBoxFor(m => m.Email, new { @class = "form-control" }). I have tried restarting the project, but I keep getting this issue. Again, I have not changed anything in the files and this is the plain vanilla default application with individual user accounts.

Here is the Login.cshtml page:

@model LoginViewModel
@{
    ViewBag.Title = "Log in";
}

<h2>@ViewBag.Title.</h2>
<div class="row">
    <div class="col-md-8">
        <section id="loginForm">
            @using (Html.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
            {
                @Html.AntiForgeryToken()
                <h4>Use a local account to log in.</h4>
                <hr />
                @Html.ValidationSummary(true, "", new { @class = "text-danger" })
                <div class="form-group">
                    @Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" })
                    <div class="col-md-10">
                        @Html.TextBoxFor(m => m.Email, new { @class = "form-control" })
                        @Html.ValidationMessageFor(m => m.Email, "", new { @class = "text-danger" })
                    </div>
                </div>
                <div class="form-group">
                    @Html.LabelFor(m => m.Password, new { @class = "col-md-2 control-label" })
                    <div class="col-md-10">
                        @Html.PasswordFor(m => m.Password, new { @class = "form-control" })
                        @Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })
                    </div>
                </div>
                <div class="form-group">
                    <div class="col-md-offset-2 col-md-10">
                        <div class="checkbox">
                            @Html.CheckBoxFor(m => m.RememberMe)
                            @Html.LabelFor(m => m.RememberMe)
                        </div>
                    </div>
                </div>
                <div class="form-group">

                        @Html.ActionLink("Forgot your password?", "ForgotPassword")
                    </p>*@
            }
        </section>
    </div>
    <div class="col-md-4">
        <section id="socialLoginForm">
