Building React Native Android app causes error "Cannot add task [...] as a task with that name already exists."

When I build my React Native project, I'm getting this error (AwesomeProject is the name of the app):

A problem occurred configuring project ':app'.
> Cannot add task ':app:prepareAwesomeProjectReactNativeLocalizationUnspecifiedLibrary' as a task with that name already exists.

Doing a stacktrace returns the following:

What is ReactNativeLocalizationUnspecifiedLibrary?

I have no clue where to start on how to debug this, and Googling is returning no results. I'm not sure what file(s) are causing the issue.

Can anyone point me in the right direction on how to resolve this?
