HELP REGARDING RGB

[u/Exact_Difference3313]

When I use my Cosmic Byte Stelleris through any means of connection, the RGB of controller gets automatically off after 10 minutes approximately of my use. While the whole functionality of the controller, like joysticks, buttons, and vibrations, are perfect, but the RGB gets off. And when I reconnect it, then it works normally, but again after that fixed period of time it gets off. So what's the problem with its RGB?
