Question RGB lights from fans don't work

[Levilevi]

Hi, my new PC is like 7 months old and for the most part, I don't use the RGB lights, usually I just have them off.But yesterday I wanted to show them to someone and, they aren't working from the Case Led button (I only use that, I didn't install any software for it)So far here is the list of things:Motherboard: Asus Prime B760M-A CSM Socket 1700Case: Gamdias Athena M6 Lite Black,Things I checked:The Aura in the Bios is all On.PC wasn't moved,Opened PC from both sides and I didn't see any loose or disconnected cable.
PD: And yes, the fans work, only the lights don't

is the 5V 3-Pin Addressable Header from the case connected to the motherboard ARGB Header?

Yes, there isn't a cable that is disconnected, I didn't touch and open the PC in months.
