ComplexHierarchicalTree freezes the application when multiple parents

Question

Dear Syncfusion,I am experiencing some issues with the ComplexHierarchicalTree diagram component.When there are nodes with only one parent, it works fine. But when adding a node with multiple parents, it freezes the app.I include here a project that reproduces the issue.Thanks for the help,Cristobal.Attachment: BlazorApp1_ed11d70f.zip

We have noticed that you have set the same value to both the
 ID and parent ID, which is not correct. ID value should be an unique
value where as parent ID value should be the ID value of its parent. For
example, in the shared code snippet, you have set the parent ID as
"CFO" and the ID name as "CFO". You cannot update it like
this. Additionally, we have shared  a modified code snippet for your
reference.Code Snippet:

protected override Task OnInitializedAsync()
     {
        
  ObjectDataSource = new List<ObjectData>()
         {
             new ObjectData() { Name
  = "CEO", Id = "CEO" },
             new ObjectData() { Name
  = "COO", Id = "COO", ParentEntities = new[] { new EntityInfoDto() { Id = "CEO", Name = "CEO" } } },
             new ObjectData() { Name
  = "CTO", Id = "CTO", ParentEntities = new[] { new EntityInfoDto() { Id = "CEO", Name = "CEO" } } },
             new ObjectData() { Name
  = "CFO", Id = "CFO", ParentEntities = new[] { new EntityInfoDto() { Id = "CEO", Name = "CFO" } } },
            new ObjectData() { Name
  = "Child", Id = "CHILD", ParentEntities = new[] { new EntityInfoDto() { Id = "COO", Name = "COO" }, new EntityInfoDto() { Id = "CTO", Name = "CTO" } } },
         };
         return base.OnInitializedAsync();
     }

We have fixed the reported issue "The application freezes when adding a node with multiple parents in a complex hierarchy layout"
and have included the fix in our weekly patch release (v24.1.44). To resolve
the reported issue, please update the "Syncfusion.Blazor.Diagram"
