reactjs - cannot find module '@babel/helper-regex' require stack

Question

I am working on this React project which i did the following steps in the project root folder.

1. yarn
2. yarn start

and it compiles and runs the first time successfully. However, after code changes (no new libraries were added), during compilation this error comes up:

./node_modules/react-dev-utils/webpackHotDevClient.js Error: [BABEL] C:UsersuserDocuments eact_project ode_modules eact-dev-utilswebpackHotDevClient.js: Cannot find module '@babel/helper-regex'

And i end up having to delete the entire node_modules and re download.. Does anyone have idea why this happens?
