You can try to solve it with the following code.

When trying to customize WordPress themes and backgrounds, a fatal error was encountered. Solution

Add the code to the current theme function template functions.php:

add_filter('wp_get_nav_menu_items', 'my_wp_get_nav_menu_items', 10, 3);
function my_wp_get_nav_menu_items($items, $menu, $args) {
foreach($items as $key => $item)
$items[$key]->description = '';
return $items;
}

After that, again The error disappears when opening the custom theme menu, but the code must remain in the theme. The problem still exists after removing it.

Another solution is to delete all menus previously created in the background, which can completely solve this problem, and then re-create the menus. I have never tried this method. If you have encountered similar problems with children's shoes, you can try it and there will be no loss.
