Collider active only from outside

Hi, I am trying to make bomberman-like game, but after placing a bomb and moving slightly, the player is moved outside the bomb collider completely. Is there any option to set for the collider to check the player after they left the collider in the first place?

I develop in 3D and have 2 objects: - Player with Character Controller - Bomb preset with box collider.

On "Fire1" press, the Bomb is placed on the players position. However, when player moves even so slightly, they are pushed out by the collider. I need the box collider to ignore the player (but only the player) until they leave but not enable re-entering it afterwards.
