Cannot read property 'forEach' of undefined
See original GitHub issueHello
I created a project using npx create-react-app my-app. If i use npm start, compilation is successful, but the page is blank.
I have not made any changes to the project.
The console contains an error:

Same here, running from npx here causes the same issue (no modifications maded)
EDIT: A workaround for now so you can keep on working: Disable the React DEV TOOLS extension on Chrome.
The problem comes from the global Hook which initiated wrong (Missing renderers prop on the object, which needs to be initiated with new Map())
