Firebase Crashlytics not generating crash report for release APKs Android

Question

After integrating Firebase Crashlytics in app, am not receiving the crash report in Firebase Crashlytics dashboard for release builds. For debug builds I am restricting to generate the report and only generating the report for release builds.

App level build.gradle file

plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'
    id 'com.google.firebase.crashlytics'
}

  buildTypes {
        def enableCrashlyticsInDebugBuild = false
        def enableCrashlyticsInReleaseBuild = true

        debug {
            minifyEnabled false
            testCoverageEnabled = true
            manifestPlaceholders = [crashlyticsEnabled:"${enableCrashlyticsInDebugBuild}"]
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.debug_signing
            manifestPlaceholders = [crashlyticsEnabled:"${enableCrashlyticsInReleaseBuild}"]
        }
    }

dependencies {
        implementation platform('com.google.firebase:firebase-bom:30.3.1')
        implementation 'com.google.firebase:firebase-crashlytics-ktx'
        implementation 'com.google.firebase:firebase-analytics-ktx'
}

Project level build.gradle file

 repositories {
        google()
        jcenter()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
        mavenCentral()
    }

    dependencies {
        classpath "com.google.firebase:firebase-crashlytics-gradle:2.9.2"
                 }

AndroidManifest.xml

 <meta-data
            android:name="firebase_crashlytics_collection_enabled"
            android:value="${crashlyticsEnabled}" />

Can anyone please suggest me where I am wrong? After checked all the SO answers didn't find out any solution.
