3D Objects in canvas are not working after resolution is changed, they behave as they have no collider box

Hello, I want to make a mobile game and I need to change the screen aspect ratio and resolution for the different displays. The game needs walls outside of the camera view in order to interact with the objects on screen such as objects bouncing against the edge of the screen. So I have walls pinned with rect transform to the edge of the screen and they work in the resolution that I set them in, but once I change the resolution they act as they have no collider box and objects pass straight through them, any ideas how to solve this problem or how can my objects on screen interact with the edge of the screen? Thank you
