In the win tablet environment, get any winid, the input box will not pop up the keyboard

The tablet's win system, qt6.6.0, I am getting the real-time image of the camera, using QLabel as a carrier to display the monitoring image, because I need to get the winid of QLabel to display it. The problem is that as long as I get the winid, the keyboard will not pop up after clicking the input box. The win tablet will pop up a keyboard after clicking the input port to get the focus, but now the keyboard is not displayed after getting the winid. As long as I comment out the winid, the keyboard can be used normally again
