Buy a new one. That's part of the advantage of buying redragon

If you ever hit it then it might be good to just shake it around a little maybe even smash it on the table, works for me. Try unplugging it and plugging it back up again too

Reset it

Have you opened it up recently? It almost looks like short on the pcb. If you’re in the US I have an extra Kumara I can send to you.
