You need to move your di.xml file from :

app/code/Vendor/Module/etc/frontend/di.xml

To

app/code/Vendor/Module/etc/di.xml

With code.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
        <plugin name="vendor_assign_default_value" type="Vendor\Module\Plugin\Checkout\Model\Checkout\LayoutProcessor" sortOrder="100"/>
    </type>
</config>
