我正在尝试更新我的一个Android项目的依赖项，但是我遇到了这个奇怪的错误。
罪魁祸首是AdMob的这一行代码（之前我使用的是20.6.0版本）：
implementation "com.google.android.gms:play-services-ads:21.0.0"
我遇到了一系列错误:
在jetified-play-services-measurement-base-20.1.2-runtime (com.google.android.gms:play-services-measurement-base:20.1.2) 和 jetified-play-services-measurement-impl-20.1.1-runtime (com.google.android.gms:play-services-measurement-impl:20.1.1)模块中都找到了重复的类com.google.android.gms.internal.measurement.zzhx。
在jetified-play-services-measurement-base-20.1.2-runtime (com.google.android.gms:play-services-measurement-base:20.1.2) 和 jetified-play-services-measurement-impl-20.1.1-runtime (com.google.android.gms:play-services-measurement-impl:20.1.1)模块中都找到了重复的类com.google.android.gms.internal.measurement.zzna。

......
以下是我在项目的build.gradle (:app)中使用的所有依赖项：
dependencies {
implementation "androidx.recyclerview:recyclerview:1.2.1"
implementation 'androidx.core:core-ktx:1.8.0'
implementation 'androidx.appcompat:appcompat:1.4.2'
implementation 'com.google.android.material:material:1.6.1'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
// Firebase & Crashlytics
implementation platform('com.google.firebase:firebase-bom:29.2.1')
implementation 'com.google.firebase:firebase-analytics-ktx'
implementation 'com.google.firebase:firebase-crashlytics-ktx'
//Navigation
implementation "androidx.navigation:navigation-fragment-ktx:2.4.2"
implementation "androidx.navigation:navigation-ui-ktx:2.4.2"
// AdMob
implementation "com.google.android.gms:play-services-ads:21.0.0"
// Style
implementation 'com.intuit.sdp:sdp-android:1.0.5'
// Play Core
implementation 'com.google.android.play:core:1.10.3'
implementation 'com.google.android.play:core-ktx:1.8.1'
// Billing
implementation "com.android.billingclient:billing-ktx:5.0.0"
}
以及 build.gradle (My App) 中的依赖项：
buildscript {
repositories {
google()
mavenCentral()
}
dependencies {
classpath "com.android.tools.build:gradle:7.1.3"
classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.4.2"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.21"
classpath "com.google.gms:google-services:4.3.10"
classpath "com.google.firebase:firebase-crashlytics-gradle:2.8.1"
}
}
是什么导致了这个错误？如果我将play-services-ads版本回滚到20.6.0，就不会出现任何错误。
感谢您的帮助。
