MatLab C Library mlfPolyfit crashes in Release version

Hi,

I am trying to support MatLab C Library mlfPolyFit function. The function works in VS2008, since we have migrated to VS2019. The mlfPolyfit function crashed the .exe file. The mlfPolyfit is mathwork C library function and there are not much information about it if it works with C++ 14/17/20 or will it work with VS2019 ( c++ 17). The function doesn't crash in debug but it crashes only in release.

Thank you.

Below is what stack shows,
