Ошибка QT: crashed. Как решить?

Всем привет! После компиляции программы выходит ошибка : Starting C:\Qt\build-SpaceRangers-Desktop_Qt_5_15_1_MSVC2015_64bit-Debug\debug\SpaceRangers.exe ...
The program has unexpectedly finished.
The process was ended forcefully. C:\Qt\build-SpaceRangers-Desktop_Qt_5_15_1_MSVC2015_64bit-Debug\debug\SpaceRangers.exe crashed. В коде ошибок нет вроде, но вот исходник:

Даже не могу предположить где заключается ошибка.

Буду благодарен за ответ.
