amazon web services – Duplicate class with Amplify and Android Navigation

I am trying to use AWS Amplify, and Android Navigation with Safe Args for Java. My project compiles properly, but crashes at runtime. The error indicates that the problem lies in the navigation classes, and playing with the modules I was using I found out that the other module causing the conflict is the one for AWS Amplify. I read on the official website that I should in this case remove the navigation library since it seems to already be included in the Amplify library. Can I still use the Navigator if I remove the implementation lines in my gradle files? Is there another way to fix this? The objective is just to be able to use both Navigation and Amplify in the same project. Thank you for the help 🙂

I am using Android Studio Bumblebee 2021.1.1 Patch 3 and my project is for Android 8.1 (Oreo).

My app level build.gradle file is

plugins {
    id 'com.android.application'

    // Safe Args
    id 'androidx.navigation.safeargs'
}

android {
    compileSdk 31

    defaultConfig {
        applicationId "com.example.myApplication"
        minSdk 27
        targetSdk 31
        versionCode 1
        versionName "0.0.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        // Support for Java 8 features (Amplify)
        coreLibraryDesugaringEnabled true
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'

    // Navigation
    def nav_version = "2.4.2"
    // Java language implementation
    implementation "androidx.navigation:navigation-ui:$nav_version"
    implementation "androidx.navigation:navigation-fragment:$nav_version"

    // Lottie
    def lottie_version = "5.0.3"

    // Amplify core dependency
    def amplify_version = "1.35.3"

    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

Project level build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.1.3' apply false
    id 'com.android.library' version '7.1.3' apply false

    // Safe Args
    id 'androidx.navigation.safeargs' version '2.4.2' apply false
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

I also added the android.useAndroidX=true and android.enableJetifier=true lines in gradle.properties.
