How do I fix this movement issue?

Currently, I’m trying to go up stairs which are made in probuilder and my character just cant go up the stairs for some reason, it seems like I need some sort of force to move my character up. My movement system is based on rb.addforce, anyone know how to fix this?

Probuilder stairs are designed for character controllers to climb up. This is because character controllers have a value called the step offset which allows you to climb steps that aren’t higher than that value with ease. However, with rigidbodies, They cant pass through or above colliders, as they dont have that step offset component. If you want to go up stairs created in probuilder, try making the mesh convex, which creates a slope-kind-of collider, (a ramp), that your player can go up.
