[RGB Button not working on Versa J25 RGB Edition]

I can't change the RGB mode on my case.

The user manual says "※Long press on RGB button for 3 seconds , fans will blink red light twice which now are controlled by MB software. And vice versa."
But whenever I press the button (long press or short press) it resets the whole PC.

I have the PC since february, and the fans were on single color since (never changed it, although didn't like the color). But I don't know how it changed to Breath Mode today and the constant color changing is bothering me a lot.

Does anyone know what could be?
