I am facing difficulty to solve it. Tried this below solution to solve it.

`configurations.all {

    exclude  module: 'conceal'
    //exclude group: 'com.facebook.conceal', module: 'conceal'
Enter fullscreen mode Exit fullscreen mode

}`

But it throws next error, which related to conceal.

FATAL EXCEPTION: create_react_context
Process: com.propstream, PID: 9831
java.lang.NoClassDefFoundError: Failed resolution of: Lcom/facebook/android/crypto/keychain/SharedPrefsBackedKeyChain;

Issue resolved. Thank you.

I am a react-native developer and there is no kotlin code in my project, I do not do any bridging.

Still Do i need to maintain any plugins or constrains related to Kotlin?
