I checked the device manager, and there's a yellow exclamation point next to the keyboard. So I did some basic troubleshooting like disabling/enabling the keyboard, updating, and reinstalling the keyboard drivers. So far, nothing has worked.
However, I have found that my function keys still work correctly. People have suggested using functions like Fn+7 and such, but those have done nothing so far.
And if it helps, I'm using a Toshiba laptop with a synaptics touchpad.
EDIT: I've also checked for viruses by first running a quick scan on Malwarebytes, then a full scan.
