Summary 💡

Material UI v5 doesn't support Next.js app directory. Even though the error comes from @emotion\react and not Material UI itself, I think this should be tracked here as well.

The "primary" error (there might be other problems once the Emotion issue is fixed) is:

TypeError: React.createContext is not a function
(sc_server)\node_modules@emotion\react\dist\emotion-element-b63ca7c6.cjs.dev.js (20:47)

Related Emotion issue: emotion-js/emotion#2928

Examples 🌈

I've created a minimal (failing) example using create-next-app: https://github.com/MidnightDesign/nextjs13-material-ui

@oliviertassinari The error message in #34893 is very different from the one I mentioned here. Also, this was meant to be kind of an overarching issue, because I think there will be more problems other than these two.
