I'm uncertain if I made changes to the app or source code prior to this error. Unfortunately, I suspect the issue lies in the functionality parts of the Kotlin in my source code. I am reaching out to professionals with the following skills and experience: - Knowledge in Kotlin and APK installations - Experience resolving 'Harmful app blocked' errors - Familiarly in identifying and fixing source code errors. Your assistance in helping me identify and rectify the source of this error, particularly in the Kotlin components, is greatly appreciated.
