Its some time ago but i added 2 lines to fix this error so maybe this helps other affected installations.

If it’s possible, the plugin-author could integrate something like this:

/wp-content/plugins/ba-plus-before-after-image-slider-free/admin.php:124

if ( isset($_POST['s201_label']) ) { // added to remove error: Fatal error: Uncaught TypeError: array_map(): Argument #2 ($array) must be of type array, null given in /wp-content/plugins/ba-plus-before-after-image-slider-free/admin.php:124
$_POST['s201_label'] = array_map('stripslashes_deep', $_POST['s201_label']);
foreach($_POST['s201_img_id'] as $slides_id=>$slides){
$data = s201_validate_post_data($slides_id, $slides);
if(strpos($slides_id, 'new_')===0){
$data['post_id'] = $post_id;
$wpdb->insert($tbl_s201_bai, $data);
$row_id = $wpdb->insert_id;
}
else{
$wpdb->update($tbl_s201_bai, $data, array('id'=>$slides_id));
}
}
} // added to remove error: Fatal error: Uncaught TypeError: array_map(): Argument #2 ($array) must be of type array, null given in /wp-content/plugins/ba-plus-before-after-image-slider-free/admin.php:124
