order place page take loading

Your question is about a WooCommerce based store. As far as I can see, the order view in the checkout loads extremely sluggishly or not at all. The reason for this could be WooCommerce settings or plugins you use that interfere at this point.

Deactivate all plugins that have anything to do with payment methods. Does it work better then? Then one of the plugins used will be responsible for the loading time.

You should ask more questions about this in the WooCommerce support forum: https://ww.wp.xz.cn/support/plugin/woocommerce/
