React-Native Build Failed app:mergeDebugAssets

I completed a react-native app for Android, and now when I try to

run npm android, I get this error:

 FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDebugAssets'.
> Error: java.lang.RuntimeException: java.lang.RuntimeException: java.nio.file.AccessDeniedException:
C:\Users\SONY\AwesomeProject\android\app\build\intermediates\merged_assets\debug\mergeDebugAssets\out\fonts

Please can you help me?

Many Thanks

React-native
