no Qt platform plugin could be initialized.

[Wunian]

Hi,
My environment is below,
Win11 + Desktop Qt 6.5.0 MSVC2019 64bit.

I created a very simple main-window, and built this program in my release-build folder.
When starting my exe file in my release-build folder, it complians "This application failed to start because no Qt platform plugin could be initialized".
May I know how I could solve this issue?
Thanks.
Have a nice day.

@Wunian If you want to start your application outside of QtCreator you need to deploy it.
See https://doc.qt.io/qt-6/windows-deployment.html

@Wunian or you set env QT_PLUGIN_PATH to Qt plugin path?

It works now when I refer what you mentioned, and https://medium.com/theskyisblue/在-windows-中-deploy-qt-apps-cf4054a5ee58
