Problem Movement with Rigidbody.velocity

Question

As shown in the figure, the capsule continues to move in the +x direction (the direction of another collision object).

The problem is that gravity does not work properly in this case.

alt text

Rigidbody.Gravity was basically used. If there is no collision except for the floor, it works correctly.

Therefore, it is not a solution to use a high value of custom gravity.

As a result of analyzing Rigidbody.Info,

Move the Capsule in the +x and +y directions.(OK)
Collides with another object.(OK)
Rigidbody.velocity.x changes to zero. (OK)
Rigidbody.velocity.y changes close to zero. (Why?)

I ask for help like this due to lack of knowledge.

It can be awkward because I used a translator.

 public class Movement : MonoBehaviour
 {
     Vector2 direction = Vector2.zero;
     Vector3 velocity = Vector3.zero;
     Rigidbody rb;
 
     [SerializeField]
     private float speed = 3f;
     [SerializeField]
     private bool isJumpPressed;
     [SerializeField]
     private float jumpHeight = 2f;
 
     private void Awake()
     {
         rb = GetComponent<Rigidbody>();
     }
 
     private void FixedUpdate()
     {
         Move();
         Jump();
     }
 
     private void Jump()
     {
         if (!isJumpPressed) return;
         
         velocity.Set(velocity.x, jumpHeight, velocity.z);
         rb.velocity = velocity;
     }
 
     private void Move()
     {
         velocity.Set(direction.x * speed, rb.velocity.y, 0f);
         rb.velocity = velocity;
     }
 
     #region Input Events
 
     public void OnMove(InputAction.CallbackContext value)
     {
         direction = value.ReadValue<Vector2>();
     }
 
     public void OnJump(InputAction.CallbackContext value)
     {
         if (value.performed)
             isJumpPressed = true;
         else
             isJumpPressed = false;
     }
 
     #endregion
 }

im new to coding and i dont rlly know much but i try putting a physics material on the wall and then turned it all to 0 and minimum and it worked fine exept when i walk into a wall i cant jump anymore until i walk into a wall again here my jumping script: public float Force;

  private bool grounded = true;
  
  void OnCollisionEnter(Collision collision)
  {
      grounded = true;

  }
  void OnCollisionExit(Collision other)
  {
     grounded = false;
  }

 void Update()
 {
     if(grounded == true)
     {
        if (Input.GetKeyDown("space"))
         {
          GetComponent<Rigidbody>().velocity = new Vector3(0, Force, 0);
         }
     }

     if(grounded == false)
     {
         return;
     }
 }

Thank you for your answer. But this code is not available. Your code is simply considering jumping. This is completely different from the direction of the solution I want.
