Erro ao executar o comando react-native run-android

Bom dia, estou com o seguinte erro:

FAILURE: Build failed with an exception.

* Where:
Script 'C:\Users\Nile\react-native\InstaluraMobile\node_modules\@react-native-community\cli-platform-android\native_modules.gradle' line: 200

* What went wrong:
A problem occurred evaluating script.
> Failed to parse React Native CLI configuration. Expected running 'npx.cmd --quiet --no-install react-native config' command from 'C:\Users\Nile\react-native\InstaluraMobile' directory to output valid JSON, but it didn't. This may be caused by npx resolving to a legacy global react-native binary. Please make sure to uninstall any global 'react-native' binaries: 'npm uninstall -g react-native react-native-cli' and try again

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Raphael, boa tarde!

Infelizmente eu não consegui reproduzir o erro, uma solução que encontrei foi, remover a pasta de compilação (build) dentro do android e ir para a pasta android e, e no terminal, digitar ./gradlew clean e depois cd.. e npx react-native run-android

Mas é realmente uma tentativa, qualquer coisa manda uma mensagem aqui que iremos te ajudar

Espero ter ajudado e bons estudos!
