Description

Steps to reproduce

Steps:

  1. Open this link to live example: https://codesandbox.io/p/devbox/q4fpmy
  2. Open terminal and execute yarn install
  3. The following warning is displayed:
➤ YN0002: │ react@workspace:. doesn't provide @types/react (p55ea0), requested by @mui/material and other dependencies.
Current behavior

When upgrading @mui/material dependency from 5.16.14 to 6.4.6 and using Yarn PnP mode, running yarn install produces a dependency warning.

Expected behavior

Usingyarn install should not produce any warning, as it was the case in MUI 5.x.

Context

I'm trying to upgrade my project from MUI 5.x to 6.x and I don't understand why this warning appears. I checked the package.json of @mui/material but I don't see any changes that could cause this issue.
I don't want to include the dependency on @types/react in my project because I don't use Typescript and including this dependency causes a strange bug when the application is built.
