Please, help!

I have a very annoying problem with Macbook air 2017 (mac OS Mojave). Keyboard light turns off totally after fully charge the battery. It happens right after 2 or 3 minutes as I unplug the charger. Tried everything: system management controller (SMC), checked and unchecked "Adjust keyboard brightness in low light", unchecked "slightly dim the display", restarted hundred times and I have done every tip I could find in the internet. Still no luck.
The most strange think is that at night, I shut down it. In the morning, when battery is fully charged, the keyboard light is working perfectly for several hours. And when I replug the charger, as soon as it's fully charged (tried to charge on 50% too but same happened), the keyboard light is missing. It's so annoying, and it happens mostly at night when I really do need the keyboard light.

Has anyone ever had this problem?
The f5-f6 keys show the bars, it's not locked but there's no light.
