In my case, Had to remove the proguard in debug Build Type by completely clearing the text file proguard-rules.pro and making minifyEnabled false in build.gradle file

  debug {
            debuggable true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
