From the home screen of a Galaxy S22 phone, when you tap the Recents button in the Navigation pane at the bottom, it will show "# active in background" at the top of the screen if you have # apps active in the background. If you then click on "# active in background", a screen will pop up labeled "Check background activity", and you will be able to force stop any of your apps that are running in the background from that screen. If you have an "app blocker" app running in the background (such as AppLock - Fingerprint from the Google Play store), you can easily force stop the "app blocker" app by doing this, which defeats the purpose of having the "app blocker" app. Is there any way to disable the "active in background" bar or the "Check background activity" window?
