Error:Invalid parameter pos in Collider.FetchPoseFromTransform because it was infinity or NaN

Script:

This error means that somewhere in your code you placed a NaN or inf inside a vector3, and it ended up in the physics engine somehow.

NaN and inf values are usually obtained by dividing by 0, but other operations like Mathf.Sqrt(-1) will give a NaN.

I couldn’t find any place where you may be dividing by 0, however you are doing a lot wrong:

Since your cube is moved fully by hand, it should be a kinematic rigidbody, and you should call rigidbody.MovePosition and rigidbody.MoveRotation to change its transform, and NEVER modify the transform directly.

If you want collisions, it should be non-kinematic, and you should only call AddForce and/or set its velocity.

You are also using Time.deltaTime in a FixedUpdate, which won’t cause bugs, but is considered bad practice.
