What is this error, please?Why can't a normal program run after QT is uninstalled?

You need to place the "qwindows.dll" inside a folder named "platforms" which should be in your application folder. You can find the dll in the plugins folder of your Qt installation.

Because you likely did not deploy it properly. Use windeployqt for that.
