Apparently, the Android App Starting Bug (launching of some Android Apps from the app grid fails) is not yet solved; see Rowenta Robots (android app) stop working on 4.6.0.11 and [4.6.0.11] App Support, app grid - ING Banking App and others are killed (closed) …
Since launching the apps from the Terminal or via settings → apps … is easy, we have at least a work around (see the links above)
