Please provide the project file (File -> Save, rename or zip .3mf) or at lease the STL so we can check the model(s). Thanks.

I checked the models it not work. I attached 3mf file.
I checked the models it not work.

I think that i not understend you. I mean that i add 3mf file in the first message. I repeat now again.

That's a .gcode file, not the project file (.3mf). To save a project file, you need to load the model again, make sure the bug reproduces, and press File -> Save...
Using the project file we should be able to reproduce the slice completely, as it contains the models in your scene as well as the settings and profiles you were using. That way we can re-run the algorithms to see where it's going wrong or why it's making this hole.

The model looks good only. what issue are you facing? Do you mean the hole is small? if so then change in design. Everything looks ok in the preview.

May be. Prusaslicer work is Ok. The model not from me. I checked the mode
The model does have a hole there.

What's wrong with the hole, exactly? Could you fill in the issue template? What is the expected behaviour and what is the behaviour that you're seeing?
