Game works in Play but not Launch

The main thing I am trying to get working is creating some bullets to shoot out from a plane

In “PLAY” mode, everything works nicely. Holding the LEFT MOUSE BUTTON fires the bullets. However, in LAUNCH, holding the LEFT MOUSE BUTTON does nothing. Ramas extra blueprint’s get mouse location and set mouse location is not working either in LAUNCH, but working in PLAY

Is there some settings that are different in packaging the game? I tried Level Blueprint → Begin Play → Enable Input (input Get Player Controller index 0)

HOWEVER: Keyboard Axis Mappings still work. But Action Mappings don’t work either (ActionMap key → Gate)

NOTE: all the things that doesn’t work have input from Get player controller player index 0
