Exception at exact same location on each build in C++

Hi, I am trying to write .mat files using C++. I am using Microsoft Visual Studio 2019 along with Qt to develop my application.

MainWindow.h

#include <QtWidgets/QMainWindow>
#include "ui_mainwindow.h"
#include "mat.h"

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = Q_NULLPTR);

private:
    Ui::MainWindowClass ui;
};

MainWindow.cpp

#include "mainwindow.h"

% Following exceptions are thrown even before starting with constructor:
% Exception thrown at 0x00007FFE85813E49 in MatFileTest2.exe: Microsoft C++ exception: mwboost::exception_detail::clone_impl<fl::filesystem::InvalidArgument> at memory location 0x000000BDFB52E410.
% Exception thrown at 0x00007FFE85813E49 in MatFileTest2.exe: Microsoft C++ exception: mwboost::exception_detail::clone_impl<fl::i18n::LcRscOpenFileFailure> at memory location 0x000000BDFB52E1B0.

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
{
    ui.setupUi(this);

    MATFile* myFile = NULL;
    mxArray* myData = NULL;
    mwSize myRow = 1000000;
    mwSize myCol = 1;
   
    myData = mxCreateDoubleMatrix(myRow, myCol, mxREAL); % Line at which below exception is thrown:
    % Exception thrown at 0x00007FFE85813E49 in MatFileTest2.exe: Microsoft C++ exception: foundation::core::except::detail::AnonymousInternalException<foundation::usm::NoActiveContextTypeError> at memory location 0x0000009D6A6FEFB8.
    % This exception complains about .pdb file not being loaded
    
    double* ary = new double[1000000];

    for(int ii = 0; ii < 1000000; ++ii){
        ary[ii] = ii*0.33;
    }

    myFile = matOpen("MATTest.mat", "w");
    mxSetData(myData, ary);
    matPutVariable(myFile, "Sweep_1", myData);
    matClose(myFile);
}

The program is running fine and it is generating the 'MATTest.mat' file. But it keeps on throwing an exception in the output. This exception is thrown even before I enter the MainWindow Constructor. The most peculiar thing about these exceptions is that no matter how many times I run the solution the location of exception being thrown doesn't change. It is always: Exception thrown at 0x00007FFE85813E49. I guess this has something to do with my .exe file but I can't help but wonder why? My .exe file should get a different pointer each time the program is run then why the exception has the exact same location?

Can someone please help me with this problem? I am unable to find any concrete information regarding how to solve this on the internet.

Below is my configuration:

System: Windows 10 Pro, Version: 2004, OS build: 19041.572

IDE: Microsoft Visual Studio Community 2019, Version 16.7.6

Matlab: R2019a (9.6.0.1072779 (win64)

EDIT 1: I have posted the same question on Stack Overflow.
