[PyQt] Get a executable file (.exe) from a .py file add a promoted class in a QWidget

[MiguelonReyes]

Hi!! guys,
I am trying to get a .exe file ready to be executed from a click of a button on a screen (QMainWindow). In fact, in the past I have done it without any issue.
In this case I am adding a chart plotter as a figure from library : matplotlib set a promoted class using a QWidget.

I have 3 files attached to run this chart plotter as a file .exe shown below:

    
def UI_GetChart(self): 
                #win32api.ShellExecute(0, "open", "C:\Python3_11\Lib\APT_ControlPanel\SC\SC002_GetChart_plotter.exe", None, ".", 0)
                #subprocess.run(["C:\Python3_11\Lib\APT_ControlPanel\SC\dist\SC002_GetChart_plotter.exe"])          
                os.system("C:\Python3_11\Lib\APT_ControlPanel\SC\SC002_GetChart_plotter.exe")
                self.key_getChart.setCheckable(False)
                self.key_getChart.setCheckable(True)
                pass
