Page failing to load with ChromeVox screen reader

Ionic Framework
1

Hello - I am encountering a problem when doing accessibility testing. When accessing an ionic app using the chrome screenreader (which is ChromeVox) the site fails to load.

The error below is presented in console. I have also verified this same behaviour happens with a brand new Ionic project. This is happening both in the most recent ionic version and in Ionic 5.
