    When closing game, once in a while I get

    A Native Collection has not been disposed, resulting in a memory leak. Allocated from:
    Code (CSharp):
    1.  
    2. Unity.Collections.NativeArray`1:.ctor(Byte[], Allocator)
    3. UnityEngine.Networking.UploadHandlerRaw:.ctor(Byte[])
    4. Unity.Services.Analytics.Internal.WebRequestHelper:CreateWebRequest(String, String, Byte[]) (at Library\PackageCache\com.unity.services.analytics@4.0.1\Runtime\Runtime\WebRequestHelper.cs:32)
    5. Unity.Services.Analytics.Internal.<FlushBufferToService>d__13:MoveNext() (at Library\PackageCache\com.unity.services.analytics@4.0.1\Runtime\Runtime\Dispatcher.cs:79)
    6. System.Runtime.CompilerServices.MoveNextRunner:InvokeMoveNext(Object)
    7. System.Threading.ExecutionContext:RunInternal(ExecutionContext, ContextCallback, Object, Boolean)
    8. System.Threading.ExecutionContext:Run(ExecutionContext, ContextCallback, Object, Boolean)
    9. System.Runtime.CompilerServices.MoveNextRunner:Run()
    10. System.Threading.Tasks.<>c:<.cctor>b__7_0(Object)
    11. UnityEngine.WorkRequest:Invoke()
    12. UnityEngine.UnitySynchronizationContext:Exec()
    13. UnityEngine.UnitySynchronizationContext:ExecuteTasks()
    14.  
    15.  
    You are probably not closing your WebRequest properly, can you please validate?

    Thank

    I have just seen this error too (with Analytics package 4.2.0), upon hitting Stop in the Editor.

    Code (CSharp):
    1. A Native Collection has not been disposed, resulting in a memory leak. Allocated from:
    2. Unity.Collections.NativeArray`1:.ctor(Byte[], Allocator) (at /Users/bokken/build/output/unity/unity/Runtime/Export/NativeArray/NativeArray.cs:69)
    3. UnityEngine.Networking.UploadHandlerRaw:.ctor(Byte[]) (at /Users/bokken/build/output/unity/unity/Modules/UnityWebRequest/Public/UploadHandler/UploadHandler.bindings.cs:95)
    4. Unity.Services.Analytics.Internal.WebRequestHelper:CreateWebRequest(String, String, Byte[]) (at Library/PackageCache/com.unity.services.analytics@4.2.0/Runtime/Runtime/WebRequestHelper.cs:32)
    5. Unity.Services.Analytics.Internal.<FlushBufferToService>d__13:MoveNext() (at Library/PackageCache/com.unity.services.analytics@4.2.0/Runtime/Runtime/Dispatcher.cs:87)
    6. System.Runtime.CompilerServices.MoveNextRunner:InvokeMoveNext(Object)
    7. System.Threading.ExecutionContext:RunInternal(ExecutionContext, ContextCallback, Object, Boolean)
    8. System.Threading.ExecutionContext:Run(ExecutionContext, ContextCallback, Object, Boolean)
    9. System.Runtime.CompilerServices.MoveNextRunner:Run()
    10. System.Threading.Tasks.<>c:<.cctor>b__7_0(Object)
    11. UnityEngine.WorkRequest:Invoke() (at /Users/bokken/build/output/unity/unity/Runtime/Export/Scripting/UnitySynchronizationContext.cs:153)
    12. UnityEngine.UnitySynchronizationContext:Exec() (at /Users/bokken/build/output/unity/unity/Runtime/Export/Scripting/UnitySynchronizationContext.cs:83)
    13. UnityEngine.UnitySynchronizationContext:ExecuteTasks() (at /Users/bokken/build/output/unity/unity/Runtime/Export/Scripting/UnitySynchronizationContext.cs:107)
    But this might be related to WebRequest's Dispose not working properly?

    Others are having issue too:
    https://forum.unity.com/threads/a-n...-disposed-resulting-in-a-memory-leak.1136068/

    Also, I have this error coming from the Playfab SDK even if they are calling Dispose on the UnityWebRequest
