Two temp solutions:

1. rename App.js to App.ts
   or
2. downgrade typescript version to 5.3.x (you need to install typescript locally)

run npm install --save-dev typescript@5.3.3

I have the latest version of VSCode and I have the same issue. Auto-imports do not work with neither MUI, nor React-bootstrap. Also I experience issues importing from react-router-dom (however after I manually import at least something from the library, auto-imports and import suggestions begin to work for the react-router-dom)

Same here... Auto imports in a monorepo stopped working correctly.

This is #57740 which was fixed by #57778 but was not backported to 5.4 (probably just missed).

You should be able to use the nightly TS extension to work around this for now.
