Advanced Custom Fields - Issue with Slick Slider in ACF v6

Question

I'm having an issue with Slick Slider in the admin preview with ACF 6 using the new block.json way to set up blocks.

I followed an ACF tutorial by Elliot here: https://www.advancedcustomfields.com/blog/building-a-custom-slider-block-in-30-minutes-with-acf/

In ACF v5 using the old method to add blocks this worked fine, but after updating to ACF 6 and using block.json the block crashes and says 'This block has encountered an error and cannot be previewed.' if I try to edit it. If I inspect and look in the console console I get this:

react-dom.min.js?ver=17.0.1:9 TypeError: Cannot read properties of null (reading 'add')

I'm using very similar code to the example in the tutorial to inisialise the slider, and it worked fine before I updated from ACF 5 to 6. The code looks like this:

(function($){

var initializeBlock = function( $block ) {
    // $block.find('img').doSomething();

    $block.find('.home_banner_content').slick({
        fade: true,
        infinite: true,
        dots: false,
        prevArrow: $('.nav_prev'),
        nextArrow: $('.nav_next'),
        autoplay: true,
        autoplaySpeed: 8000,
        speed: 1500,
        pauseOnHover: false,
        pauseOnFocus: false,
    });
}

// Initialize each block on page load (front end).
$(document).ready(function(){
    $('.home_slider_block').each(function(){
        initializeBlock( $(this) );
    });
});

// Initialize dynamic block preview (editor).
if( window.acf ) {
    window.acf.addAction( 'render_block_preview/type=home-slider-block', initializeBlock );
} 
})(jQuery);
