Lottie Player got deleted immediately after page load

Folks my Lottie player HTML element is got deleted every time the page loads. The website is on WordPress and the Lottie player code is infused through a custom plugin. It is working fine on this website strucurecore.net but on this site, blueprintee.com animation just shows and got deleted. Even if I try to inspect the code It is not there where it has to be. Just see this Screenshot:

The code which is deleted is:

<lottie-player src="'.plugin_dir_url(__FILE__).'/assets/fetching.json" background="transparent" speed="1" style="width: 300px; height: 300px; margin:auto;z-index:99;position:relative;margin-bottom: -150px;" loop autoplay></lottie-player>

The Elementor Pro plugin is installed on the site. So any hack to avoid the deletion of the Lottie player element?

Thanks.`
