Crash on VFuncSwapHook/VTableSwapHook Constructor

I am absolutely losing my mind. I tried to hook a DirectX 11 function based off https://github.com/stevemk14ebr/PolyHook_2_0/blob/master/UnitTests/windows/TestVFuncSwapHook.cpp

Before constructing VFuncSwapHook hook, redir map is valid: The moment it enters the constructor, redir which should have been passed by reference is completely invalid: The program crashes on m_redirectMap(redirectMap) as it appears to be trying to construct a map based on an invalid map. I am running in x64 debug mode, no optimizations should be applied here.
