Import error when using Material UI styles with React router v7 framework

[kayden1940]

Steps to reproduce

Similar to this one mui/material-ui#42544
A fresh start of React router v7 framework template, installing and importing ReactRouterAppProvider yield below:

Directory import '/repo/packages/web/node_modules/.pnpm/@toolpad+core@0.12.0_@emotion+react@11.14.0_@types+react@19.0.8_react@19.0.0__@emotion+styled_eyl2qwst7e3srdiktssoojso7e/node_modules/@mui/material/styles' is not supported resolving ES modules imported from /repo/packages/web/node_modules/.pnpm/@toolpad+core@0.12.0_@emotion+react@11.14.0_@types+react@19.0.8_react@19.0.0__@emotion+styled_eyl2qwst7e3srdiktssoojso7e/node_modules/@toolpad/core/AppProvider/AppProvider.js Did you mean to import "@mui/material/node/styles/index.js"?
adding ssr noExternal in vite.config doesn't solve it.

I believe this would be solved by #4676

A fresh start of React router v7 framework template

@kayden1940 which template are you talking about? Can you share a github link?

#4686 will fix the import, but some extra setup will be needed to make sure the styles and the theme work correctly with SSR. See https://mui.com/material-ui/guides/server-rendering/
