In this [issue](https://github.com/facebook/react/issues/23373), when you navigate to [this app](https://next-rsc-notes.vercel.app/note/1646289027680) and inspect the sidebar in the components tab, you will get this error:

 This is a user error. One of the components in the user's app thrown. However, the UI for this is confusing, because it seems like it's a DevTools error. We've gotten a lot of bug reports like this, and it would be good to differentiate between DevTools bugs and bugs in the app. For this task:

- [ ] Build the React DevTools extension locally (instructions [here](https://github.com/facebook/react/tree/main/packages/react-devtools-extensions)) and reproduce the error
- [ ] Figure out a way to have the front end be able to differentiate whether the error is a error within DevTools or within the user's app
- [ ] Design/implement a better UI to help app developers distinguish between these two cases
