Why aren't my collisions working unity 2D

I am a new game dev who is learning unity. I made sure that trigger was not ticked. I have a circle and a box collider. I have a rigged body on the circle one. I also have a trigger that also doesn’t detect collisions. It is a flappy bird game.

You should confirm layer collision matrix in physics setting.
if you do not check the layers, you can’t detect collisions.
