QT Creator bar menu dissapear when opening QMainWindow ui file

Hi Everybody,

I am using Qt Creator v11.0.3 in Windows 10. When I open a UI file with the QMainWindow type, the Qt Creator window will close automatically and reopen automatically. However, when it was reopened, the menu bar and others disappeared. This behavior will not happen when I open the UI file for the QDialog type.

This is when I open the Design for QDialog UI file

I tried the older Qt Creator v5.0.3, and it is working fine.

Hopefully, someone has a solution for this issue. Thank you.
