Need a Very Simple Beaver Builder Function

I need to write a custom plugin that clears the Beaver Builder cache BEFORE a Saved Row is “Saved” (ie. updated) for ANY Saved Row template.

I’ve tried this code but when I click “Publish” on a Saved Row (from the front end) it just hangs.
ie. doesn’t publish

Any thoughts?

<?php
/**
 * Plugin Name: Clear BB Cache Before Saved Row Update
 * Description: Clears the Beaver Builder cache before updating any Saved Row.
 * Author: Yours Truly
 * Version: 1.1
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly.
}

// Hook into Beaver Builder's before save layout action.
add_action( 'fl_builder_before_save_layout', 'clear_bb_cache_before_update_saved_row', 10, 2 );

/**
 * Clear Beaver Builder Cache Before Updating Saved Rows
 *
 * @param int $post_id The post ID.
 * @param array $data The layout data.
 */
function clear_bb_cache_before_update_saved_row( $post_id, $data ) {
    // Check if the post is a saved row.
    if ( 'fl-builder-template' === get_post_type( $post_id ) ) {
        // Clear the Beaver Builder cache.
        if ( class_exists( 'FLBuilderModel' ) ) {
            FLBuilderModel::delete_asset_cache();
            FLBuilderModel::delete_all_transients();
        }
    }
}
