      Just to make sure: Does the deployed version of Qt5Widgets.dll match your application's Qt version?

          Please search the forum - it's full of exactly this question.
          Hint: you most likely forgot to deploy the plugin (by not using windeployqt) or some dlls are missing by the plugin -> Dependency Walker
