Player's Collider Stuck Help

The blue bars are the walls of my game. The problem is that when the player(the green cube) is falling it gets stuck between the two walls colliders(that are aligned perfectly)…
(the player and the walls have a box collider 2d)
How can i resolve this?
p.s. for this game i can’t make a big collider which includes all the walls…
