Your code works if you fix the typo:

$_helper = $this->helper('Magento\Catalog\Helper\Output');
$_product = $block->getProduct();

$productAttributes=$_product->getAttributes();
        $group_id=9;
        $attributeSetId=4;
        foreach ($productAttributes as $attribute) {
            if ($attribute->isInGroup($attributeSetId, $group_id)) {
             echo $attribute->getFrontendLabel().' : '.$attribute->getFrontend()->getValue($_product).'<br />';
            }

    }
