disturb, prevent, hamper, obstruct
妨 centers on interference that blocks or slows something: disturbing a process, preventing an action, or obstructing progress.
妨 combines 女 (woman) with 方, which likely contributes the sound. The exact historical reason for the woman component is uncertain, but the character has long carried the sense of hindering or obstructing.
A woman 女 stands beside a direction 方, blocking the way. She is disturbing the path and preventing you from passing.
For ボウ, imagine a bow (as in bow and arrow) being used to obstruct a path: bow -> ボウ, and the woman uses it to hamper your progress.
