I have used my Nano for several months without any issue, both through the Python and Javascript APIs.  
Both my PCs do not recognize the device anymore. They have Windows 11 Home 22000.978.

How to check if it’s an issues with some recent Windows updates or the stick itself?

The stick could be fried, or you might have to [uninstall a driver, etc.](https://answers.microsoft.com/en-us/windows/forum/all/unknown-usb-device-device-descriptor-request/a2806a43-23b4-44b6-9e3f-557c4995dda3)
