Opencv trackbar crash when I slide

C++
3

I can’t show all the code but, to give an exemple of what I wrote and where is the problem locate.

 {
    int lowHue =0
    int lowSaturation = 0
    int lowValue = 0
    int highHue = 255;


     cv::namedWindow("Configuration");

	cv::createTrackbar("Low hue","Configuration", &lowHue, 255, OnChangeLowHue, this);
	cv::createTrackbar("Low saturation","Configuration", &lowSaturation, 255, OnChangeLowSaturation, this);
	cv::createTrackbar("Low Value", "Configuration", &lowValue, 255, OnChangeLowValue, this);
	cv::createTrackbar("High hue", "Configuration", &highHue, 255, OnChangeHighHue, this);

}

static void Window::OnChangeLowHue(int lowHue, void * thisWindow)
{
    Window* that = (Window*) thisWindow;
    that->Foo.LowHue(lowHue);
}
static void Window::OnChangeHighHue(int highHue, void * thisWindow)
{
    Window * that = (Window*) thisWindow;
    that->Foo.HighHue(highHue);
}

......

The opencv version is 4.2 and I install on Ubuntu 20.4 with de package : sudo apt install libopencv-dev

No I don’t debug it.
