cant play game because of InternalEngineBridge error

so i'm very new to unity, even if i have been using it for a couple months. and i have been developing a meh game. everything was fine, until i tried to play the game i had made(in the unity editor) and then it spat out this error:

.

Library\PackageCache\com.unity.2d.common@2.0.2\Runtime\InternalBridge\InternalEngineBridge.cs(15,48): error CS1503: Argument 2: cannot convert from 'Unity.Collections.NativeArray' to 'Unity.Collections.NativeArray'

.

an i had no idea what this was. so i double clicked on it. and i found the line that is causing the error. It is line 15 of the InternalEngineBridge.cs script.

 using UnityEngine.UIElements;
 using Unity.Collections;
 
 namespace UnityEngine.U2D.Common
 {
     internal static class InternalEngineBridge
     {
         public static void SetLocalAABB(SpriteRenderer spriteRenderer, Bounds aabb)
         {
             spriteRenderer.SetLocalAABB(aabb);
         }
 
         public static void SetDeformableBuffer(SpriteRenderer spriteRenderer, NativeArray<byte> src)
         {
             spriteRenderer.SetDeformableBuffer(src); //here is the line that caused the error.
         }
 
         public static Vector2 GUIUnclip(Vector2 v)
         {
             return GUIClip.Unclip(v);
         }
 
         public static Rect GetGUIClipTopMostRect()
         {
             return GUIClip.topmostRect;
         }
 
         public static Rect GetGUIClipTopRect()
         {
             return GUIClip.GetTopRect();
         }
 
 #if UNITY_EDITOR
         public static void SetLocalEulerHint(Transform t)
         {
             t.SetLocalEulerHint(t.GetLocalEulerAngles(t.rotationOrder));
         }
 
         public static bool IsChecked(this VisualElement element)
         {
             return (element.pseudoStates & PseudoStates.Checked) == PseudoStates.Checked;
         }
 
         public static void SetChecked(this VisualElement element, bool isChecked)
         {
             if (isChecked)
             {
                 element.pseudoStates |= PseudoStates.Checked;
             }
             else
             {
                 element.pseudoStates &= ~PseudoStates.Checked;
             }
         }
 
 #endif
     }
 }

and it sucs alot. does anybody know what to do?
