Player passing through walls when in corners

The character is stopped by the colliders in the walls but if I continue to walk towards an corner, it goes through the colliders.

This is what is happening:

The character’s Rigidbody and Capsule Collider:

Both walls have Box Colliders within them.

The code that governs the player walk is this:

void FixedUpdate()
    movement = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
    _rigidBody.MovePosition(_rigidBody.position + movement * Velocity * Time.deltaTime); //Velocity = 10

I know it’s been a while, but I ran into this problem and couldn’t any solutions online.

If you are controlling movement by changing transform.position manually, you allow your character to ever so slightly clip into a wall by running into it.
This is not a huge problem on its own, but if you then run diagonally into a corner it will push your character fully through the wall.

I simply changed my implementation to change RigidBody.velocity.

New implementation:

gameObject.GetComponent<Rigidbody>().velocity = MoveSpeed * movement.normalized;

Old implementation:

transform.position += (MoveSpeed * Time.fixedDeltaTime * movement);

That solved it for me.
