Maybe an issue with your theme level: app/design/frontend/YourThemeVendor/YourTheme/Magento_Customer/layout/default.xml

Compare this file with vendor/magento/module-customer/view/frontend/layout/default.xml

You need to pass view_model like:

<block class="Magento\Customer\Block\Account\AuthenticationPopup" name="authentication-popup" as="authentication-popup" template="Magento_Customer::account/authentication-popup.phtml">
    <arguments>
        <argument name="jsLayout" xsi:type="array">
            <item name="components" xsi:type="array">
                <item name="authenticationPopup" xsi:type="array">
                    <item name="component" xsi:type="string">Magento_Customer/js/view/authentication-popup</item>
                    <item name="children" xsi:type="array">
                        <item name="messages" xsi:type="array">
                            <item name="component" xsi:type="string">Magento_Ui/js/view/messages</item>
                            <item name="displayArea" xsi:type="string">messages</item>
                        </item>
                    </item>
                </item>
            </item>
        </argument>
        <argument name="view_model" xsi:type="object">Magento\Customer\ViewModel\Customer\StoreConfig</argument>
    </arguments>
</block>
