App crash for C++/CLI DLL and exe of x64 bit

Just to showcase problem I have written a simple DLL x64 of "Hello world" changed its property to CLR and Calling its Function from an Exe which is also x64 and property Changed to CLR.

But My exe prints the Output "Hello World" and crashes every time and gives FAULT Module Name KERNELBASE.dll.

When I change Property of both to NO CLR it works perfectly fine. This happens only for x64 application not observed in x86 program.

I am using Visual Studio 2017 on Windows Server 2012.

It will be very helpful if someone can guide me to correct direction.
