I can't see the screen composition in the right pane in qt designer.

I am new to qt.

I can't see the screen composition in the right pane in qt designer.
I don't know if this has anything to do with it, but the alert window is floating in the window on the left.

please help me.

The QML file has a reference to a version of Qt Quick that you do not have. You would need Qt 5.10 or later to have v1.3 of Qt Quick.

What version or version of the Qt libraries have you got installed?
What version of the Qt library is in use in your Qt Creator project settings?

First of all, thanks for the reply.
The current qt version is 6.3.2, and the qt build version is 5.15.2.
I'm not sure where to check the library you mentioned.
