My Pawn Doesn't move when I hit play button

My Pawn Doesn’t move

I even can control my character by
hitting “A,S,W,D” keys. What can i do
to prevent this ?

The title and the description contradict. I will assume that the issue is that the character can be controlled while you’re in the menu.

You’re setting Input Mode to Game / UI Only on Begin Play in 2 separate blueprints. Instead set the Input Mode to Game when the user exits the menu.
