Inconsistent jump height when rotating character left or right

I am developing an endless runner mobile game, Similar to Subway Surfers. I make my player character rotate slightly left or right and then return to facing forward when sliding left or right. The issue is that this rotation makes the character's jump inconsistent, resulting in different jump heights.

How can I make the jump consistent? Below are the scripts I am using.

In the PlayerController script:

public void SetVelocity(Vector3 velocity)
{
    CController.Move(velocity * Time.deltaTime);

    //Rotate the player a bit where is going
    Vector3 dir = CController.velocity;
    if (dir != Vector3.zero)
    {
        dir.y = 0;
        transform.forward = Vector3.Lerp(transform.forward, dir, data.RotationSpeed * Time.deltaTime);
    }
}

In PlayerJumping script:

public override void Enter()
{
    player.velocityY = data.jumpForce;
}

private void UpdateJumpMovement()
{
    // Aplly gravity
    player.velocityY += data.gravity * Time.deltaTime;

    Vector3 pos = Vector3.zero;

    pos.x = player.SnapToLane();
    pos.y = player.velocityY;
    pos.z = player.currentSpeed;

    player.SetVelocity(pos);
}
