On my mac m1, it is added to accessibility and enabled, also it does not crash randomly, only every time my mac either falls asleep or when I put it to sleep. Sometimes I get lucky and it freezes with the settings I use, but most of the time it defaults to the rainbow pattern. I use a Corsair K95 and scimitar elite. On my windows machine it works always. I do have it connected to a switch, that could be it, but really, it shouldn't. On my windows machine it is connected to the same switch and never, ever any issues. If the switch is indeed the cause, it is imho a matter of poor development
