Module reads package from java.xml and stax.api

Question

I am trying to make a javaFX application that can send SMS through a SaaS called Twilio. I am getting an error when I import Twilio onto intelliJ. I am using JDK 11.0.3 and javaFX 11.0.2.

At first I had two projects, one where I created the code to send SMS (as well as other backend logic) and another to create the front-end. Individually they work great, but once I add the SMS code to the front-end project, it stops working.

My module-info if that helps:

module MassCommsFrontV3 {
    requires javafx.fxml;
    requires javafx.controls;
    requires twilio;

    opens sample;
}

I am not quite sure why this is a problem. I have read online that it could have with Twilio's dependencies interfering with my project dependencies, but I'm not really sure what that means.

EDIT: Runtime exception that occurs after deleting module-info:
