qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""



  • Trying to start a Qml/C++ application in debugger with Qt 5.14.1 MinGW 64 bit

    The console output shows:

    QML debugging is enabled. Only use this in a safe environment.
    qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
    This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
    

    and I see in Qt creator this nessage box
    a1c38a75-649a-4b52-8906-1bdeca8fe4fe-image.png

    It is on Windows 10 64 bit with latest Qt creator V4.11.1.

    Any idea what the cause could be?



  • In the installatiopn are some plugins missing.
