npm run watch não vai até o fim

Olá, Ao executar o comando run npm watch, ele fica parado no app\util\ProxyFactory.js atualizei minha versão do node para a 12.14.1 (versão recomendada no site). Podem me ajudar, pois não consigo prosseguir no curso.

Ele fica parado na linha acima, já deixei por um bom tempo e ele não sai dela.
