Unable to open visual editor on wordpress page

Hi there,
Thanks in advance for your help.
When trying to edit this page with the visual editor switched on, I get the following error:

TypeError: Object(...) is not a function

It turns out to be a conflict with the Yoast plugin. I don’t want to disable it completely and remove the SEO data.

It only happens on the one (about) page. This is the code of the template of this page:

<?php
/**
 * Page Template
 *
 * Template Name: About Template
 *
 */
get_header(); ?>

    <?php get_template_part('banners/page-banner-with-hero'); ?>

<?php if (have_posts()) : ?>

    <?php while (have_posts()) : the_post(); ?>
    <div class="container page-about">

        <div class="row">

           <div class="col-lg-5">
               <img src="<?php bloginfo('template_url'); ?>/_/img/pru_chapman_elin_bandmann_photography-77a-copy.jpg" alt="">
           </div>
           <div class="col-lg-7">
               <h1>Victoria's Story</h1>
               <?php the_content(); ?>
           </div>

        </div><!-- /row -->

    </div> <!-- /container -->

        <div class="container-fluid page-about-invest">
            <div class="row">
                <div class="col-lg-8 offset-lg-2">
                    <h3>When you invest in your future through our work,<br/>
                        you’re also creating a meaningful change in the world.
                    </h3>
                    <a href="" class="btn btn-primary btn-orange">Start Now</a>

                </div>
            </div>
        </div>

        <div class="container page-about-video">
            <div class="row">
                <div class="col-md-10 offset-md-1">
                    <div class="embed-container">
                        <iframe width="560" height="315" src="https://www.youtube.com/embed/Ew8TIM2nvJ4?rel=0&controls=0&showinfo=0&modestbranding=1" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen=""></iframe>
                    </div>
                </div>
            </div>
        </div>
    <?php endwhile; ?>

<?php else : ?>

    <?php get_template_part('loop/loop-error'); ?>

<?php endif; ?>

<?php get_footer(); ?>

Would be so grateful if anyone could help!!
Thanks ??
