I attached the 3 log files for you, hope it helps.

Before the window disappears, it always says the following in the log files:

[2019-02-27T20:28:21.617 CET WARN ][default] - QWidget::paintEngine: Should no longer be called
[2019-02-27T20:28:21.618 CET WARN ][default] - QPainter::begin: Paint device returned engine == 0, type: 1
