Wordpress code snippet bug, youtube videos not embedded

I added a code snippet to add elements between paragraphs on blog posts, but somehow when this snippet is active it prevents youtube videos from being embedded. The job is to fix this bug. sample [login to view URL] here is the code snippet: //'[vc_row][vc_column width="1/1"][uncode_block id="325528"][/vc_column][/vc_row] ', function addParagraphs($content) { if (is_single() && !(is_product())){ $the_category = get_the_category()[0]; // you can add as many as you want: $additions = array( '<a href="[login to view URL]"> <button style="background-color: #037ffc; border: none; color: white; padding: 10px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; cursor: pointer; margin: 4px 2px; border-radius: 5px;"> Support me on Patreon </button> </a>', '<p>[Sassy_Follow_Icons]</p>', '<a href="[login to view URL]"> <button style="background-color: #037ffc; border: none; color: white; padding: 10px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; cursor: pointer; margin: 4px 2px; border-radius: 5px;"> Book me as a cosplayer </button> </a>', '<p>[publishpress_authors_box layout="ppma_boxes_876899"]</p>', '<a href="[login to view URL]"> <button style="background-color: #037ffc; border: none; color: white; padding: 10px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; cursor: pointer; margin: 4px 2px; border-radius: 5px;"> Join our Discord server <3 </button> </a>', '<a href="[login to view URL]"> <button style="background-color: #037ffc; border: none; color: white; padding: 10px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; cursor: pointer; margin: 4px 2px; border-radius: 5px;"> Instagram <3 </button> </a>', '<a href="[login to view URL]@snowicosplay"> <button style="background-color: #037ffc; border: none; color: white; padding: 10px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; cursor: pointer; margin: 4px 2px; border-radius: 5px;"> Tiktok <3 </button> </a>', ); $content = get_the_content(); $output = ''; // define variable to avoid PHP warnings $parts = explode("</p>", $content); $count = count($parts); // call count() only once, it's faster for($i=0; $i<$count; $i++) { $output .= $parts[$i] ?? ''; $output .= '</p>'; $output .= $additions[$i] ?? ''; if ($i % 5 === 0) { $output .= '[products per_page="2" columns="2" orderby="rand" order="rand"]'; } // non-existent additions does not concatenate } return $output; } else { return $content; } } add_filter('the_content', 'addParagraphs', 20);
