The player passes through the collider of the prefab, but everything works on manually placed objects

Problem: The player passes through the collider of the prefab, but everything works on manually placed objects

I’m a beginner, I googled a lot, and I tried everything - from changing collision detection to FixedUpdate, but the problem remains.

What could be the reason, given that if I put the prefab manually on the scene, everything works fine?

Make sure your player and prefab collider component is not trigger
