Hiii,
ACF validation error messages disable and publish button loaded infinite, as per my testing it’s working fine if deactivate WPML(Purchased) Plugin
Either there is a JavaScript error or there is a PHP error during the AJAX request that is interfering with the request or the response of the request. You need to track down where the error is happening. It you don’t see a JS error then use the WP error log to look for errors during the AJAX request https://codex.wordpress.org/WP_DEBUG
