Erro ao executar react-native run-android - outro erro

Boa dia a todos. Estou fazendo um curso de React-Native e já estou na 10ª aula. Estou rodando o projeto do curso via Depuração USB no celular. Até então, tudo rodava funcionava direitinho mas agora react-native run-android passou a apresentar esses erros:

To reload the app press "r"
To open developer menu press "d"

O que pode ser ?
Obrigado.
