Debug Assertion Failed! Expression: __acrt_first_block == header when using libtorch debug build

I built libtorch 1.6 from source (with /MTd switch). Everything went smoothly!
but upon executing the test application it crashes with this error

you can see the whole source code so its just a simple hello world
Whats wrong here? Any help is greatly appreciated

note: I’m building using Visual Studio 2019
