tried running following doesn’t work

bin/magento setup:upgrade

bin/magento setup:di:compile

bin/magento setup:static-content:deploy -f 

bin/magento indexer:reindex

<type name="MagentoCatalogModelResourceModelProductIndexerPriceBatchSizeCalculator">
    <arguments>
        <argument name="batchRowsCount" xsi:type="array">
            <item name="default" xsi:type="number">1000</item>
        </argument>
