I tried to reproduce your issue, but didn't experience any problem under Windows 22H2.
Would the 3D preview be updated when you resize the dialog box or select a material in the list?

Always the same problem.
The first object takes 20 to 30 seconds to appear.
The following depends on their origin:
1. internal objects appear after 5 sec
2. objects imported after 10 sec.
Resizing the window does not change anything.
