Hello,
Sorry to hear about that.
As far as we are seeing the Product Page of your Site, it is showing an Error in the Console related to wp-includes which is usually related to WordPress end: https://ibb.co/HrM6Pqk
Because we can’t seem to find any Errors related to this on our Test Site. So, it isn’t a Theme end issue.
So, please kindly once try contacting the WordPress Support in this regard and see what they have to say in this regard. They will guide you through.
Best Regards
