The windows application I made up by Qt 5.9 sometimes ends unexpectedly!

[Qt_crazyer]

I am making up an application about OpenGL, but it sometimes ends unexpectedly. The application output tells me about this:
ASSERT: "childIface" in file accessible\qaccessibleobject.cpp, line 127.
I don't know what it's! But when I recompile program after restarting my computer, this problem doesn't appear. So when I have this problem, I have to restart my computer again. It's crazy! I want to know what's this problem and how to solve it.

@Qt_crazyer Why do you have to reboot your computer? Does your app not start again without rebooting? I don't know whether this ASSERT is the reason for the crash. You should run your up through debugger to see what really happens.

Thank you for your reply. Maybe I don't explain this problem clearly. This problem just only happens occasionally. Once it happens, it keeps coming up. When I try debuging, that's not going to happen again. So, I choose to restart my computer. Maybe there's a better solution, but I don't know how to do.

@JNBarchan
It's great. I just use this function: QWidget::createWindowContainer. Maybe I can try to modify the code. Thank you for your reply.
