How resolve the `Unresolved Allocations` which is shown in MSVC for Memory Diagnostic?

Hi all,

I am trying to figure out memory leak in my game with MSVC plus UE 5.0.
In ‘DebugGame’ configuration, most of memory is shown as unresolved allocations when I take a snapshot in VS. The DebugGame Edtior is as well.
How to resolve this problem? Any helps is appreciate!!
