How This Error Occurs ?

Caused by: java.lang.ClassNotFoundException: com.android.build.api.extension.AndroidComponentsExtension

How To Solve Caused by: java.lang.ClassNotFoundException: com.android.build.api.extension.AndroidComponentsExtension Error ?

Solution 1: Update Navigation Safe Args versions

Here As per Android Gradle Plugin 7.1.0 release notes

AGP APIs that the Navigation Safe Args Gradle plugin depend on have been removed. AGP 7.1 does not work with Navigation Safe Args versions 2.4.0-rc1 or 2.4.0, but will work with versions 2.5.0-alpha01 and 2.4.1

Navigation Safe Args version 2.4.1 not Released yet So that we have to use Safe Args 2.5.0-alpha01 to fix this incompatibility. Just Add this line in your dependencies.

dependencies {
    .
    .
    .

    // Just Update this line and use 2.5.0-alpha01
    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.5.0-alpha01"

    .
    .
    .
}

Now, Your error must be solved. Thank You.

Solution 2: Use This

plugins {
    id 'com.android.application' version '7.1.0' apply false
    id 'com.android.library' version '7.1.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.6.10' apply false
    id 'androidx.navigation.safeargs.kotlin' version '2.4.0' apply false // Working fine
//    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.4.0" // Not working now

}
