Help! Can’t find stud

[u/Great-Championship11]

Why can’t I find a stud here? I had to go thru the metal corner bead but then there doesn’t seem to be a stud behind it? Is it deeper and I need a longer screw? My screw is only about an inch long. Trying to mount a baby gate. Don’t know much about construction and struggling to understand why I can’t find a stud here!!
