We would like to help you but we don’t see any PHP errors or something that could guide us why your site requires such a lot of resources.
We found Slow queries from the Subscriptio plugin https://prnt.sc/p6tr89 Do you have products with the subscriptions? Do you use that plugin or keep that plugin just in case? If you don’t use the functionality of the plugin then disable it.
Also, could you contact your hosting provider and ask them if they have any detailed reports what requests (from what plugins or theme requests) cause such problem with your memory because we don’t have an idea what could be the reason of that problem. We want to help you but checked theme options and don’t have an idea why this happens. We are ready even to give you refund if you think that our theme is the main problem of this.
