Hey I am not getting your issue could you brief that?

I've seen it a few times now, developing a React Native Expo app using Expo Go. I reload the app with DevTools open and I get this error.

Uncaught Error: Cannot add node "1734" because a node with that id is already in the Store.

Refreshing DevTools doesn't help.

I encountered the same issue because I had installed the React Developer Tools extension twice, likely from two different sources. Removing one of them resolved the issue for me.

We fixed some scenarios where this could occur in React DevTools 7.0. If this issue still persists, please open a new issue.
