Unable to Apply External Forces to my Rigidbody

When using rigidbody.AddExplosionForce(), my player only goes up, He isnt effected on the X or Z axis, I believe its because of the way the players velocity is handled, or its the ForceMode (Impulse), If i use ForceMode.Force (The explosion works when its ForceMode.Force), It feels terrible and its just not as good as the instant velocity changes with the Impulse ForceMode, Here is my code:

     void Movement() {
             // Calculate how fast we should be moving
             Vector3 targetVelocity = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
             targetVelocity = transform.TransformDirection(targetVelocity);
             targetVelocity *= speed;
             
             // Apply a force that attempts to reach our target velocity
             Vector3 velocity = rb.velocity;
             Vector3 velocityChange = (targetVelocity - velocity);
             velocityChange.x = Mathf.Clamp(velocityChange.x, -maxVelocityChange, maxVelocityChange);
             velocityChange.z = Mathf.Clamp(velocityChange.z, -maxVelocityChange, maxVelocityChange);
             velocityChange.y = 0;

             rb.AddForce(velocityChange, ForceMode.VelocityChange);
             
             // Apply Gravity
             rb.AddForce(new Vector3(0, -gravity * rb.mass, 0));
         }
 

Anyway, I have no clue how to get around this, Because i need to use AddExplosionForce as it is a big mechanic in my game. And yes, Im using ExplosionForce correctly, It was working before I changed my movement script, Because my old movement script was unreliable and generally bad.

Thank you for your time :)
