on 0.62.2 gradlew assembleRelease fails on Flipper dependency

After upgrading to ./gradlew clean debugRelease works and build is successful, but assembleRelease fails with error on importing Flipper method on ReactNativeFlipper.java

if debugImplementation in app/build.gradle are changed to implementation, build is done successfully. But I don’t think it’s right approach to include Flipper in release version.

//         debugImplementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}") {
        implementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}") {
          exclude group:'com.facebook.fbjni'
        }

//         debugImplementation("com.facebook.flipper:flipper-network-plugin:${FLIPPER_VERSION}") {
        implementation("com.facebook.flipper:flipper-network-plugin:${FLIPPER_VERSION}") {
            exclude group:'com.facebook.flipper'
        }

//         debugImplementation("com.facebook.flipper:flipper-fresco-plugin:${FLIPPER_VERSION}") {
        implementation("com.facebook.flipper:flipper-fresco-plugin:${FLIPPER_VERSION}") {
            exclude group:'com.facebook.flipper'
        }

I have found wokraround. app level build gradle:

            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"

            signingConfig signingConfigs.release

            sourceSets {
                main {
                    java {
                        exclude 'com/{path_to_file}/ReactNativeFlipper.java'
                    }
                }
            }
        }
    }
    ...

MainApplication.java
