Hello,
Problem is not related to our theme because we found the report about the same issue on the WooCommerce MPGS plugin support forum https://wordpress.org/support/topic/fatal-error-3440/
You see our plugin in the Stack trace because we use that default WooCommerce function get_total(). It seems that the mentioned plugin is the reason of the error and it causes the problem not just in WooCommerce plugin files but also in our plugin files because we also use that function.
Try to disable the mentioned plugin and proceed to checkout again.
