Runtime error when referencing external library in Unreal Engine

Development Programming & Scripting

I followed the steps from this tutorial:

https://wiki.unrealengine.com/How_to_Link_External_C_Libraries_.dll_.lib_With_Your_Project_%26_Package_With_Game,_Fast_And_Easy

I was able to successively reference the external c++ library and the project compiles just fine. However, at runtime, when I instantiate an object from external library, I get the following error:

Exception thrown at 0x00007FFD7244FD31
(mscordacwks.dll) in UE4Editor.exe:
0xC0000005: Access violation reading
location 0x0000000000000000. occurred
Source information is missing from the
debug information for this module

and the stack is:

the line where the error occurs:

CSharpClassExposer* scharpClassExposer = nullptr;
scharpClassExposer = new CSharpClassExposer();

The external library that I am referencing is C++ CLI (managed C++) which further wraps C# dll and I am sure it has something to do with this. However, in my separate test project where I use the same managed library with native c++ console client instead of Unreal Engine, it all works fine.
