LED keyboard not turn ON when and after playing BF 2042, why ?

1. Why won't the Caps Lock, Num Lock, and Scroll Lock LEDs on my Fantech Atom 107 mechanical keyboard light up (even though the Caps Lock key is still fully functional)?

2. This only happens when playing Battlefield 2042, whereas previously, the Caps Lock LED was still on normally when playing Counter-Strike 2 and War Thunder. I played all three games through the Steam app.

3. I'm still using Windows 10 22h2 full update and I don't use any additional programs from Fantech!

4. I'm using a Fantech MK893S Atom 107S Mizu Edition mechanical keyboard!
