Recently there have been some issues with Windows updates, and have caused issues with some gaming USB keyboards. Please check if your Windows OS build number is 17134.165 or later. 

If it is, please consider uninstalling Windows security update KB4338819, from your update history. 

For continuous issues, please close all Fnatic related software in your task manager. In start-up settings, also consider disabling Fnatic software from opening on boot.
