MethodName(out IntPtr variableName) send null values for out parameter from the iOS Binding dll in .NET 8

Question

GeList(out IntPtr variableName) send null values for out parameter from the iOS Binding dll in .NET 8 .NET 8 iOS binding library project . Method in ApiDefinition class.

//iOS Binding Library Project ApiDefinition.cs 
// @required -(RESULT)getList:(NSMutableArray **)availableList; 
[Export("getList:")] Result getList(out IntPtr availableList);

in .NET 7 if we call above method in MAUI SAMPLE APP the availableList will received.

// MAUI app 
//Get avilable List 
NSMutableArray availableList = new NSMutableArray(); 
IntPtr availableHandle = availableList.Handle; 
Result availableListResult = apiInstance.getList(out availableHandle); 
availableList = ObjCRuntime.Runtime.GetNSObject<NSMutableArray>(availableHandle); 
if (availableListResult == Result.Success) 
{ 
System.Diagnostics.Debug.WriteLine("Success " + availableList);
 } 

But in .NET 8 if we call above method in MAUI SAMPLE APP the availableList will get Null , but not in .Net 7 (can get availableList ). Any solution for .Net 8 ?.  

In .NET 8 if I call getList method in MAUI SAMPLE APP the availableList will get Null , but not in .Net 7 (can get availableList )
