FN+Arrow Keys no longer change aura brightness of the keyboard_ Brand New Asus TUF A15 FA506QM

[rnogueira611]

System: Windows 10 Pro 64bits
Battery or AC: Both
Model: Asus TUF A15 FA506QM (R7 5800H + RTX 3060 + 16gb 3200mhz)
Frequency of occurrence: Always happening, since a few days ago

Screenshot or video: -
========================
Detailed description：Every Hotkey works perfectly, including the FN+RIGHT/LEFT hotkey to change the aura mode, but the FN+UP/DOWN stopped working a few days, I haven't done anything in particular to cause this problem, the pc is brand new, i got it 10 days ago, it is pretty much stock.
Help please.
Also, when I run diagnostics on MyAsus app, it doesn't let me see the result for some reason.
