In the ajax call this code is injected as json response
Seems to be
/vendor/maxserv/magento-module-yoastseo/view/adminhtml/templates/score.phtml

<div class="yoastScore-wrapper" data-bind="scope: 'yoastScore'">
    <div class="yoastScore-header">
        <span><strong>SEO Score</strong></span>
    </div>
    <div class="yoastScore admin__field">
        <span class="admin__field-label" data-bind="i18n: 'Keyword'"></span>
        <span data-bind="attr: {'class': keyword_class}"></span>
        <span data-bind="text: keyword_label"></span>
    </div>
    <div class="yoastScore admin__field">
        <span class="admin__field-label" data-bind="i18n: 'Readability'"></span>
        <span data-bind="attr: {'class': content_class}"></span>
        <span data-bind="text: content_label"></span>
    </div>
</div>
<script type="text/x-magento-init">
    {
        ".yoastScore": {
            "Magento_Ui/js/core/app": {
                "components": {
                    "yoastScore": {
                        "component": "MaxServ_YoastSeo/js/view/yoast-score"
                    }
                }
            }
        }
    }
</script>

Solved it for now by changing the
/vendor/maxserv/magento-module-yoastseo/view/adminhtml/layout/yoastbox.xml

FROM line 6

        <referenceContainer name="content">
            <block class="MaxServ\YoastSeo\Block\Adminhtml\Score" name="yoast.score" template="MaxServ_YoastSeo::score.phtml" before="-" />
        </referenceContainer>

TO

        <referenceContainer name="page.content">
            <block class="MaxServ\YoastSeo\Block\Adminhtml\Score" name="yoast.score" template="MaxServ_YoastSeo::score.phtml" after="page.main.actions" />
        </referenceContainer>
