If you encounter this issue while publishing a Windows project, you can resolve it by following these steps:

  • Start by checking the project folder structure.
  • In my case, as shown in the screenshot below, the Process.xaml file was initially located inside the Process folder. To resolve the issue, I moved the Process.xaml file out of the Process folder and then deleted the unnecessary Process folder.

While this issue does not occur when publishing project in the Legacy, it seems to be present in the windows project
