I'm trying to popen a Kivy app bundled using pyinstaller from a Windows service and it fails to open, throwing

Try upgrading your graphics drivers and/or your graphics hardware in case of problems.
But the thing is, my GPU runs with open gl 4.6
When I execute it usually :

I saw many people complain about it but the thing is, that app runs as expected when running it normally (without the service popening it / standalone).
I saw some issues mentioned to change to angle_sdl2 but it throws another error saying "A valuable windows provider was not found". I found out that it used GL 3.2 instead of 4.6
Turning on to only sdl threw the same error.
I've finally solved it !
@inclement you were right ! it was indeed running in a different environment and changing the environment only didn't make up for the working.
the services run in a totally different environment and has restricted access to the logged-in user's desktop interface.
I tried to explain it in detail here : Pystray icon available when running as a service
it worked for me !
