Thank you for reaching out to us with your question. Unfortunately, your photos are blurry and I cannot see the details of the fruit. Could you send us a closer and clearer photo of one of the fruits that have symptoms, please?

Thank you for sending these additional photos.

These look like symptoms of rust, a type of fungal disease. Several species of rust can infect pears (and apples) and cause the fruits to become deformed. Rust diseases can occur if Juniper trees are nearby. https://extension.umd.edu/resource/apple-and-pear-diseases

It is too late to spray a fungicide for this now. A fungicide will not cure the symptoms that are already present. Remove the infected fruit and consider spraying early next year with a protectant fungicide. You can follow the Home Fruit Disease and Pest Prevention spray schedule found on our website: https://extension.umd.edu/resource/home-fruit-disease-and-pest-prevention-spray-schedule
