Please note that changing the Stripe payment description from Order #, to Product Title is not recommended and might lead to a possible site issue as the details are required by the plugin to perform further actions.
However, if you wish to proceed with making the changes, I would suggest reaching out to a developer, as this involves custom coding and implementations. The WooCommerce community is filled with talented open-source developers, and many of them are active on the channels listed below:
Hope this helps!
