How to prevent a Python standalone one-file executable created with FileCapture from opening the console?

[PriyanshuChandel]

I have a Python GUI application built using Tkinter and Matplotlib. This GUI generates graphs by decoding network packets. The core functionality of the program relies on pyshark, and I've included a simplified code snippet below for reference:

from pyshark import FileCapture
file_path = 'FileSource.pcapng'
capture = FileCapture(file_path)

The code works perfectly when running it from an IDE. However, when I create a standalone executable using Nuitka, it opens a command prompt console window alongside the GUI, which doesn't look aesthetically pleasing in the GUI application.

I've noticed that this console window only appears when running the application as an executable. When running the application from an IDE, there is no console window.

My question is: How can I prevent this console window from appearing when running the application as a standalone executable while still retaining the functionality of the program?

Note - Please do not confuse with the console opened by exe for python, this console is not opened by exe for python but getting opened only when above mentioned code is getting executed
