Error: "Minified React error" in React dev tools when using Components tab

Do you want to request a feature or report a bug? Bug

What is the current behavior? React Dev tools gets this error when I try to look at the Components Tab

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn’t have dependencies other than React. Paste the link to your JSFiddle (https://jsfiddle.net/Luktwrdm/) or CodeSandbox (https://codesandbox.io/s/new) example below: I don’t know how to reproduce it. It was working yesterday and not working today.

What is the expected behavior? That the Components tab of the React dev tools doesn’t crash.

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React? 16.6.3

Here is what I see. It’s not my React app crashing. It’s the dev tools.
