    I have tried to deploy a project with QT Multimedia components using Qt 6.6.1 but I get the following errors:
    could not load multimedia backend ""
    QtMultimedia is not currently supported on this platform or compiler.
    Failed to initialize QMediaCaptureSession "Not available"
    Failed to initialize QMediaRecorder "Not available"
    Failed to create QVideoSink "Not available"
    Failed to initialize QCamera "Not available"

    However, the "multimedia" directory within the executable directory has the appropriate plugin files ("windowsmediaplugin.dll" and "ffmpegmediaplugin.dll"). Note that the project compiles and runs fine, just it fails when deployed. Did anyone encounter the same or similar error?

      It works in release mode, but not in debug mode. The latest version is the same
