Had the same problem with Shopware version 6.4.15.0.
Fixed the issue by changing the services.xml.

From:

<service id="RecentlyViewedProduct\DAL\FieldSerializer\RecentProductFieldSerializer">
    <argument type="service" id="Shopware\Core\Framework\DataAbstractionLayer\DefinitionInstanceRegistry"/>
    <argument type="service" id="validator"/>

    <tag name="shopware.field_serializer"/>
</service>

To:

<service id="RecentlyViewedProduct\DAL\FieldSerializer\RecentProductFieldSerializer">
    <argument type="service" id="validator"/>
    <argument type="service" id="Shopware\Core\Framework\DataAbstractionLayer\DefinitionInstanceRegistry"/>

    <tag name="shopware.field_serializer"/>
</service>

The order of the params has switched in the newest version of Shopware.
