[GRASS-user] [d.*] command not executing from standalone script

[Ang Sherpa]

This initiates the grass gis and will be running background.
subprocess.Popen(['cmd','/K','grass72 -text'],cwd=gisbase)

However, the d.mon does not open even after executing
from grass.script.setup import set_gui_path
set_gui_path()

Am I still missing something?

I also tried running by directly injecting 'd.mon start=wx1' command to the
subprocess itself. With this approach I got an error as stated in ##ERROR
(as shown in attachement_2)
subprocess.Popen(['cmd','/K','grass72 -text','*d.mon start=wx1*
'],cwd=gisbase)

##ERROR: Cleaning up temporary files...
Starting GRASS GIS...
ERROR: <C:\Users\WRPPF-A> is not a valid GRASS Location because PERMANENT
Mapset is missing
Exiting...
Press any key to continue . . .

I have attached the my script herewith this mail.
Will be looking forward to hearing from you.
