Chuwi Hi12 not detecting stylus hipen H3

I Installed Microsoft Windows 10 from Microsoft site and after that my tablet Chuwi hi12 is not detecting my stylus H3 which was working fine until then. So I reinstalled windows that was provided to me by Chuwi support but still my tablet is not detecting my stylus.
My tablet model number is CWI520.
Following image shows drivers that are installed/present now.
Note-Stylus Is not defective. After reinstalling windows that Chuwi support provided all windows updates are taken
What should I do now? please help
Thank you.
