How can I fix a a npm/yarn start issue?

Question

    yarn run v1.22.10
$ react-scripts start
node:internal/modules/cjs/loader:488
      throw e;
      ^

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/tokenize' is not defined by "exports" in /home/victor/Desktop/epitech/tek3/project/B-DEV-500-NCE-5-1-dashboard-victor.sorais/epiboard/node_modules/postcss-safe-parser/node_modules/postcss/package.json

  code: 'ERR_PACKAGE_PATH_NOT_EXPORTED'
}

I created a react app with npx-create-app <app_name>, but i don't understand what is the problem, I've already updated all my package, tested rm all webpack package and npm install and more other option. Any idea ?

You can temporarily fix this issue by downgrading the node version to 16.13.0. If you are running it on mac you can install nodeV16.

brew install node@16

It seems a lot of people are facing these issues with the latest node version. I am attaching some links which might help you resolve this (link1 and link2) if above thing doesn't work.

Note: remove the existing version and install a new fresh one. You can check this link to remove it completely(I am not writing same commands with description as a lot people already explained it)
