MyAppHiltApp: java.lang.ClassNotFoundException: Didn't find class "HiltApp" on path: DexPathList

Question

I have a problem how to fix java.lang.RuntimeException: Unable to instantiate application com.example.bettehomes.MyAppHiltApp: java.lang.ClassNotFoundException: Didn't find class "com.example.bettehomes.BetteHomesHiltApp" on path: DexPathList. My package name is "com.example.bettehomes". I tried clean and rebuild.

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.bettehomes">

    <application
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/Theme.BetteHomes"
        android:name=".BetteHomesHiltApp"
        >
        <activity
            android:name=".BetteHomesActivity"
            android:exported="true"
            android:theme="@style/Theme.BetteHomes.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data
            android:name="com.google.firebase.messaging.default_notification_icon"
            android:resource="@mipmap/ic_launcher" />
        <meta-data
            android:name="com.google.firebase.messaging.default_notification_color"
            android:resource="@color/dark_orange" />
        <meta-data
            android:name="com.google.firebase.messaging.default_notification_channel_id"
            android:value="@string/default_notification_channel_id" />
        <meta-data
            android:name="firebase_performance_logcat_enabled"
            android:value="true" />
    </application>

The logcat shows:

FATAL EXCEPTION: main Process: com.example.bettehomes, PID: 27056

What eventually worked was: What worked for ClassNotFound in hilt app was: (of course added kotlin-kapt plugin id and id com.google.dagger.hilt.android in app's build.gradle) using JAVA 18.

`implementation "com.google.dagger:hilt-android:${hilt_version}" (2.46)
implementation 'androidx.hilt:hilt-navigation-compose:1.0.0'
kapt 'androidx.hilt:hilt-compiler:1.0.0'
kapt 'com.google.dagger:hilt-android-compiler:${hilt_version}'`

For android gradle plugin`7.4.2` kotlin `1.8.20` compose `1.4.6`
