Please help. We have page on WordPress with our custom theme and minimum plugins. After update WordPress from 4.9 to 5.0.2 we have error in the admin page on Themes => Customize. Everything else is working.

I try turn off and on foreign plugins (except WP bakery). Thanks.

Fatal error: Uncaught Exception:
Supplied nav_menu_item value missing property: description in /wp-includes/customize/class-wp-customize-nav-menu-item-setting.php:183

Stack trace:

• Do you have any menu items created from PHP code? – Krzysiek Dróżdż Commented Dec 25, 2018 at 17:30
• I was only able to fix this by deleting my menus and recreating them. – Joel Newcomer Commented Dec 22, 2019 at 14:41

I have an update on this. I discovered that if a menu item has ACF fields assigned to it and you delete a menu item, it causes this error in the Customizer. It seems as if the menu item delete functions are leaving ACF data behind in the database which is causing this. I have reached out to ACF support regarding the issue.
