Qt WinRT app crashes when changing title bar color

Cobra91151

I want to create the WinRT app using Qt 5.15.8. The issue is when I add the following code to change the app title bar color:

.h file

#include <winrt/Windows.System.Diagnostics.h>
#include <winrt/Windows.UI.ViewManagement.h>
#include <winrt/Windows.Foundation.h>

using namespace winrt;
using namespace Windows::System::Diagnostics;
using namespace Windows::UI;
using namespace Windows::UI::ViewManagement;
using namespace Windows::Foundation;

.cpp file:

auto titleBar = ApplicationView::GetForCurrentView().TitleBar();
titleBar.BackgroundColor(ColorHelper::FromArgb(255, 54, 60, 116));
titleBar.ForegroundColor(ColorHelper::FromArgb(255, 232, 211, 162));

The program just exits (crashes).
I run the debugger but it still the same, the app just exits. It's a simple app, can someone reproduce this issue?

Dialog::Dialog(QWidget *parent)
    : QDialog(parent)
{
    QPushButton *btn = new QPushButton("Click", this);
    btn->setGeometry(250, 400, 100, 100);
    connect(btn, &QPushButton::clicked, [this]() {
        ApplicationView appView = ApplicationView::GetForCurrentView();

        if (appView) {
            qDebug() << "Success!";
            auto titleBar = appView.TitleBar();
            titleBar.BackgroundColor(ColorHelper::FromArgb(255, 54, 60, 116));
            titleBar.ForegroundColor(ColorHelper::FromArgb(255, 232, 211, 162));
        } else {
            qDebug() << "Failed!!!";
        }
    });
}

I have Windows 10 Version 22H2 installed. Developer mode is enabled. It just exits whithout any return from ApplicationView instance.

Any ideas why this code leads to such issue? Thank you.
