Laravel blade mail data not rendered – Blancer.com Tutorials and projects

I have a mail view named passwordReset.blade.php like this

<!DOCTYPE html>
<html>
<head>
    <title>Wachtwoord Reset</title>
    <style>
        body {
            font-family: "Calibri", sans-serif;
            color: #000000;
            font-size: 0.9167em;
        }
        .token {
            color: #00a9b5;
            font-weight: bold;
        }
    </style>
</head>
<body>
    <p>Beste gebruiker van de ,</p>
    <p>
        Er is een aanvraag gedaan voor het herstellen van je wachtwoord. Ben je dit niet geweest dan mag je deze e-mail negeren. Voor het opnieuw instellen van je wachtwoord voer je de onderstaande code in bij de app:
    </p>
    <p class="token">
        {{ $code }}
    </p>
    <p>
        Let op! Deze code is 30 minuten geldig.
    </p>

    <p>
        Hartelijke groet,
    </p>
</body>
</html>

But in the mail the code stays like this: {{ $code }}

This is my mailable class:

<?php

namespace AppMail;

use IlluminateBusQueueable;
use IlluminateContractsQueueShouldQueue;
use IlluminateMailMailable;
use IlluminateMailMailablesContent;
use IlluminateMailMailablesEnvelope;
use IlluminateQueueSerializesModels;
use AppModelsUser;

class PasswordResetNew extends Mailable
{
    use Queueable, SerializesModels;

    private User $user;
    /**
     * Create a new message instance.
     */
    public function __construct(User $user)
    {
        $this->user = $user;
    }

    /**
     * Get the message content definition.
     */
    public function content(): Content
    {
        return new Content(
            view: 'emails.passwordReset',
            with: [
                'code' => $this->user->USER_WACHTWOORD_RESETCODE,

            ],
        );
    }

    /**
     * Get the attachments for the message.
     *
     * @return array<int, IlluminateMailMailablesAttachment>
     */
    public function attachments(): array
    {
        return [];
    }
}

And i have already debugged and the value is not empty before in the constructor and content functions.

And this mail gets called like this:
Mail::to($user->USER_EMAIL)
->send(new PasswordResetNew($user));

Thanks
