My react native project build fails somehow because of this error:

Execution failed for task ':app:mergeDebugNativeLibs'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.MergeNativeLibsTask$MergeNativeLibsTaskWorkAction
   > 2 files found with path 'lib/arm64-v8a/libfbjni.so' from inputs:

     If you are using jniLibs and CMake IMPORTED targets, see

Anybody got a clue what could cause the build to fail? I haven't edited any build file and/or removed/installed/upgraded new packages thanks

For me this worked (after reading Tony's link), my version of react was 0.66.0
Changed this file android\app\build.gradle

implementation "com.facebook.react:react-native: "  // From node_modules

to

implementation "com.facebook.react:react-native:0.66.0!!"  // From node_modules

Same issue here. It's happen 12 hours ago and basically before that I didn't change anything in code.

Here's a workaround to fix this problem if you are not using latest version of react-native. https://github.com/facebook/react-native/issues/35210
