Changing scene in Model.cpp fails

[starcin]

I have a hardware trigger that needs to change a scene (think a Home button but I cannot use a hardware key event).

I am trying to change the scene for days but I cannot find a working solution.

The best looking solution was this: https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/how-to-implement-quot-switchscreen-quot-in-touchgfx/m-p/384809

Using this method crashes the code. Well technically the code is stuck in this loop in syscalls.c:

void _exit (int status)
{
  _kill(status, -1);
  while (1) {}    /* Make sure we hang here */
}

My code in the model is like this:

void Model::tick()
{
	uint16_t buttonState = getButtonState(16);
    if (buttonState != previousButtonState)
    {
        if (modelListener != 0)
        {
            modelListener->onButtonStateChange(buttonState);
        }
        if (static_cast<ButtonEnum>(buttonState) == ButtonEnum::MENU)
        {
            static_cast<FrontendApplication*>(Application::getInstance())->gotoSplashScreenScreenNoTransition();
        }
        previousButtonState = buttonState;
    }
}

I also tried to increase the minimum heap size since I saw it may be the cause.

The gotoSplashScreenNoTransition() is automatically generated since it is may entrance point.
