React native installed but build keeps failing

[JulianHSC]

i've tried:
-changing build.gradle, changing gradle file in gradle-wrapper.properties (gradle 8.3 to 7.6),
-invalidate cache, changing ports
and these don't work.

The following is the error message. I hope someone can help:

C:\Z-Android\ReactNative>npx react-native run-android
info A dev server is already running for this project on port 8081.
info Installing the app...

info 💡 Tip: Make sure that you have set up your development environment correctly, by running npx react-native doctor. To read more about doctor command visit: https://github.com/react-native-community/cli/blob/main/packages/cli-doctor/README.md#doctor
