Need help with sprites

Hi so i’m new programming with unity, and I got my code all set and running. there is one problem, whenever I start my game… this happens: https://drive.google.com/file/d/1tAbC7E2ppvotENnvpaTaSiCcZncnOqn4/view?usp=sharing ← video file. If someone experienced can help me, please let me know.

have you added colliders in the sprites?

no will try that

I tried colliders but it still goes through the road. it is a image I made myself, not sure if that is different from a cube.

is it using 2d or 3d colliders and then matching 2d or 3d physics (rigidbody)?

I tried that, now the road and the sprite falls

I am using 2D physics, my main sprite has rigidbody only
