QML Video does not work with explorer.exe shut down

On Windows while explorer.exe is shut down any video cannot be played (using QML Video component).

When I try to play a video with explorer.exe running Video has following values:

status = 6
availability = 0
bufferProgress = 1
error = 0
errorString = ""
playbackState = 1
position = 57

When I try to play a video (.mp4) with explorer.exe shut down Video has following values:

status = 6
availability = 0
bufferProgress = 0
error = 0
errorString = ""
playbackState = 1
position = 0

The problem seems to appear when this line is present in C++ before loading QML:
QGuiApplication::setAttribute(Qt::AA_UseOpenGLES);
Without this line Video works correctly without explorer.exe
