    As per error there is no any parent id name with mgs so it will throw error.

    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">
<menu>
    <add id="Magento_Cms::cms_page" title="Pages" module="Magento_Cms" sortOrder="0" parent="Magento_Backend::content_elements" action="cms/page" resource="Magento_Cms::page"/>
    <add id="Magento_Cms::cms_block" title="Blocks" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::content_elements" action="cms/block" resource="Magento_Cms::block"/>
</menu>

    In the code above parent="Magento_Backend::content_elements" will display in content menu so give valid id to your menu then it will work.

    Just modify the menu file located under /vendor/magento/module-cms/etc/adminthml/menu.xml

    <add id="Magento_Backend::mgs" title="Blocks" translate="title" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::mgs" action="cms/block" resource="Magento_Cms::block"/>

    Here’s how it’ll look
