On the Chuwi Hi10X tab stylus(H6) does not work, but the finger touch works

Hello, forum. The stylus has stopped working on my Chuwi Hi10X tablet, but the screen itself works and reacts to touch. The stylus is Chuwi HiPen H6. The serial number of the tablet is HI10 XG128G210******.
All the drivers that I found did not fit or do not work.

I have the exact same problem, but with a H7. Changed batteries, pen tip and still no stylus.
