Good Morning Rikard!
With a fresh WordPress 6.7.2 & Enfold 7 installation using the Enfold “DJ Demo,” the error did not initially occur.
After installing YOAST SEO and adjusting a few Enfold settings to match my standard configuration, the issue reappeared.

I went through each setting step-by-step and identified a clear cause:
When setting the option “Integrated (Bundled) LayerSlider Plugin” to “Deactivate but leave plugin files in theme folder,” the backend audio player error immediately occurs.

You’ll be pleased to hear that neither YOAST SEO nor the performance settings for CSS/JS file compression & merging have anything to do with this issue.

Simply put:
LayerSlider off → audio player broken. 🙂

Best Regards,
Mischa

Thank you for your help.

Unfortunately, the problem also occurs for me from version 7.0 onwards, even without a child theme.
I have made a short video demonstrating the issue:
(see private content)

Audio files can be selected and rearranged, but after adding them, the playlist remains empty in the settings window.

Best regards,
Mischa

PS:
I have created a temporary fix for the avia-builder.js from line 2324.

// Put this in avia-builder.js at line 2324:
$(this).each(function() {
  // Check if update_html is a string or an array before using indexOf
  if (typeof update_html === 'string' || Array.isArray(update_html)) {
    if (update_html.indexOf('avia_builder_') !== -1) {
      // code to process the update ...
       if( update_html.indexOf( '###avia64###:' ) !== -1 ) {
		//	encode base64 string
		update_html = update_html.replace( '###avia64###:', '' );
		update_html = atob( update_html );
	}
    }
  } else {
    // Handle the case where update_html is not a string or array
    console.error('update_html is not a string or array:', update_html);
  }
});
