US International keyboard deadkeys stopped working

Since yesterday, the deadkeys for any marks like ` ~ ' " stopped working. It acts as if I've pressed the key twice so two of the same character appear at once, instead of nothing happening until I press another key. I can't put any accents on letters anymore and it's just very annoying overall. How do I fix this? I've already tried everything in the keyboard settings and updating/reinstalling the keyboard driver. Upon restarting the computer it works properly for, like, a minute, and then it goes right back to being broken. Any help would be greatly appreciated!

    1

    Go into the keyboard settings and switch your keyboard form the US English International keyboard to just the US English keyboard, restart (not shut down) your PC and then go back into settings and set the keyboard language back to US English International keyboard.

    2

    If that does not resolve the problem:

    Open Command Prompt, then paste in this command and press Enter:

    msdt.exe -id KeyboardDiagnostic

    Run that Keyboard Troubleshooter to see if that can solve the problem.
