FN+UP/DOWN no longer change aura brightness of the keyboard, and SN shows error. FA506QM

[糖白咕咕雪]

System: WIndows 11 Home
Battery or AC: Both
Model: FA506QM (R7-5800H RTX-3060)
Frequency of occurrence: Always
Reset OS: Nope
Screenshot or video: Nope
========================
Detailed description：
Every Hotkey works perfectly, including the FN+RIGHT/LEFT hotkey to change the aura mode, But FN+UP/DOWN has not been working properly for a long time.
By the way, both in BIOS and in MyASUS, the SN is SSN12345678901234567, this is not consistent with the SN of the computer itself.
I've tried updating the BIOS but it didn't work.
Now my BIOS version is 309.
Below is the post I found that had a similar problem to me:

 I tried many ways to fix the problem, but I couldn't solved that by myself. I need help, please!
