Usually it is recommended to alao write something when you open a new thread. Also use of search would be recommended.
As we dont know what you have already done do tou happen to have a Windows hello capable webcam by any chance?
As @inffy mentioned your topic is missing some information!
Do you e.g. use a Microsoft Account? Windows Hello does need it to log in, otherwise it won’t work.
If this does not resolve your issue, do you have reinstalled your Windows? Did you already try reinstalling the ‘Sensors’ driver-pack from the Eve Support page?
Windows has been newly created and fixed.
