Missing Camera on GemiBook Pro

GemiBook Pro VC150I1
Camera disappeared after installing windows 11. How do I get it back?

The camera disappeared; some magician was nearby.

Now seriously: Why did you reinstall Windows ?
Have you Googled: “What to do after installing Windows” ?

I had windows 10.

You can download the drivers from the Chuwi website.
The problem might be that they only have drivers for Windows 10.
