React version: 18.0.0-alpha-bd255700d-20210816 or main branch

Steps To Reproduce

1. Use ReactDOM development from alpha version or main branch
2. Call ReactDOM.render() or ReactDOM.createRoot(...).render()

If you open DevTools you can see the error which is preventing rendering. If you change the scripts from development.js to production.min.js, you can see the problem go away.
