Can't move my pawn when it's box collider collision

Hello Sam, Hope you’re doing good. Sam, In this lecture I’ve come across an issue that when I change my box collider’s collision preset from no collision to any other collision preset. Then my pawn stops moving, it’s movement completely gets blocked.
Also, I changed collision to block all dynamic when this issue first appeared. I’m attaching a screen shot for you to take a look.

Looking forward to your assistance.
Thanks in advance.

Have you checked the collider is not colliding with the ground? The box looks too low at the moment and would collide with the ground stopping movement. See attached image. There is a bit on one of the videos where the box is adjusted. See the video from about 1.30 onwards which scales the box then lowers the car inside the box so the wheels are just out of the bottom.
