Can't load library qtquickcontrols2basicstyleplugin.dll

[kimvnhung]

I'm trying to create a QQuickWidget in Qt C++ , generating python module using shiboken and using it in a python sample.
A testing sample in C++ works perfect without error.
But while I use the generated python module it showed the window with entirely white color on the QQuickWidget.
The log from python here.
