Both Ctrl keys now working

As the title says, each of my manage keys are no longer functioning - and this is extra than using me insane. I have, so far, checked for new driver updates, as nicely as reinstalling my keyboard driver, to no success.

The on display keyboard, when I toggle control, does work. Likewise, when examined on this website online https://keyboardtestt.com/ all keys aside from manipulate appear to work.

I am the usage of an ASUS laptop computer (X540L), and my modern-day Windows model is Windows 10 - Version 1803 (OS Build 17134.285)

As a ways as I know, I have not added any adjustments well worth noting that would purpose this. I am past stressed, as this is slowing my work significantly. Any feedback would be of help!
