You can momentarily downgrade react-scripts to 1.1.5 in the package.json file, then remove the node_modules folder and in the case of using NPM delete the package-lock.json file and in case Yarn delete the file yarn.lock. After that, reinstall the dependencies and start the development server with the yarn start or npm run start command.
