create-react-native-app: Can't create a new app

Description

I’m running commands like create-react-native-app foo, but they’re failing. They’ve worked in the past with the same setup (same versions of node, yarn, OS, same network, etc.) - I think it may be an issue with a package that create-react-native-app depends on (duplexer3) being removed from the npm registry?

Expected Behavior

I expected a new react native app skeleton to be created.

Observed Behavior

create-react-native-app foo failed with output:

Creating a new React Native app in /Users/yashapodeswa/projects/foo.
