[Dúvida] webpack não reconhe modulo fs

criei um app usando npx-create-react-app e depois baixei o modulo dotenv para usar variáveis de ambiente, mas na hora de compilar o webpack está dando o erro:

Module not found: Error: Can't resolve 'fs' in 'C:\{caminho}\casaverde\node_modules\dotenv\lib'
ERROR in ./node_modules/dotenv/lib/main.js 1:11-24
Module not found: Error: Can't resolve 'fs' in 'C:\{caminho}\casaverde\node_modules\dotenv\lib'

ERROR in ./node_modules/dotenv/lib/main.js 2:13-28
Module not found: Error: Can't resolve 'path' in 'C:\{caminho}\casaverde\node_modules\dotenv\lib'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.   
This is no longer the case. Verify if you need this module and configure a polyfill for it.   

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "path": require.resolve("path-browserify") }'   
        - install 'path-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "path": false }

No console web o erro é:

Uncaught Error: Cannot find module 'fs'
