qdarktheme Import Issue:
The most immediate issue is that qdarktheme might not be available, and you mentioned earlier that there was trouble installing it. Since qdarkstyle was successfully installed, you should replace the qdarktheme usage with qdarkstyle.

Update the section where qdarktheme is used:

Original:

import qdarktheme
Replace with:

import qdarkstyle

Also, replace the theme setup line:

Original:

qdarktheme.setup_theme()
Replace with:

app.setStyleSheet(qdarkstyle.load_stylesheet())
