Today Infinity isn't working anymore

I was playing Dark Souls with “Unlimited Humanity” which is very useful to get items and level up bonfires but today it stopped working, toggle keys are not working, I can’t edit any key, only with my Xbox controller (usb), can’t use any other cheat like Unlimited Health, keys don’t work. Unplugging my controller does nothing.

Edit: I’ve tried with other games, same result.

Do the cheats stay blue or turn off ? Which dark souls ? (1,2 or 3?).

Cheats aren’t working at all, they’re all turned off. Tried with DS1 and Fallout 4 with same result.
