The program is completed due to the lack of layout management on the form

I'm trying to use a virtual keyboard (https://www.linux-apps.com/p/1132203).
I noticed a very strange thing. If you remove the linker on the form, the program terminates with an error

Error - RtlWerpReportException failed with status code :-1073741823. Will try to launch the process directly

With the vertical line-up everything works.
An error occurs when the focus is changed (if you click on another qLineEdit) in file examplemyfocus.cpp in line

((Tester*)this->parent())->getKeyboard()->focusThis(this);

((Tester*)this->parent())->getKeyboard()->focusThis(this);

Because of what it can happen?
