ClassCastException while building signed Apk

My gradle dependency is

     repositories {
        google()
        mavenCentral()
//        maven { url "http://maven.ghostscript.com" }
        maven { url 'https://jitpack.io' }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

Use these app dependency

     buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }


    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'

        exclude 'META-INF/LICENSE.txt'
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

        }
    }

    implementation 'io.reactivex.rxjava3:rxandroid:3.0.0'

    implementation files('libs/aspose-words-17.2.0-android.jar')
    implementation "com.folioreader:folioreader:0.5.4"

}

While creating release signed Apk this error occurs, how can I solve it? Cannot solve these error while delete gradle cache and also invalidate and restart Android Studio.

java.lang.ClassCastException: com.android.tools.r8.s.b.C cannot be cast to com.android.tools.r8.s.b.B

com.android.tools.r8.CompilationFailedException: Compilation failed to complete, position:Lorg/readium/r2/streamer/parser/epub/OPFParser;parseSpine(Lorg/readium/r2/shared/parser/xml/Node;Lorg/readium/r2/shared/Publication;)V, origin: C:\Users\Asif Malik.gradle\caches\transforms2\files2.1\202fad4fee5b15436e55e2114f613e17\jetified-r2streamerkotlin1.0.42runtime.jar:org/readium/r2/streamer/parser/epub/OPFParser.class

Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)

Re-download dependencies and sync project (requires network)

The state of a Gradle build process (daemon) may be corrupt

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        ndk {
            debugSymbolLevel 'SYMBOL_TABLE'
        }
    }
}

Set minifyEnabled false solved my issue .go to build.gradle and do this change
