Chuwi Minibook: keyboard not working in Windows 10 21H1

My keyboard is not working in the latest Windows 10 (21H1), OS build 19043.844.

I already downloaded all drivers from this link:
NY08 drivers (

But got confused about which one is the keyboard driver.
Can you help me with the solution?

Device info:
Chuwi Minibook m3-8100Y
Windows 10 Home version 21H1

There is no keyboard driver for it. If it’s not working then it must be something else. Try opening the hinge and closing it.

I think it is truly a hardware problem. Sometimes, the keyboard is typing by itself repeatedly on some keys.
Any pointer on how I should prie open this Minibook?
