Latest version 6.5.2

With the latest version, 6.5.2, that was supposed to “Fix: Sanitize custom field value before being inserted into post.” but it broke my custom field shortcode. The shortcode gets a Text Area custom field from ACF. The Text Area has HTML in it that display a video. It has been working perfectly for several years but after the 6.5.2 update, the shortcode only shows a blank section on the website. The pages are behind a paywall so let me know if you need temp access.
