I used the Danish keyboard layout(win11) for both italian and Danish, because Italian needs àèéìòù and that language setting allowed me to type those. when I pressed the key next to backspace it waited until I pressed a vowel and it would write the vowel with the accent. if you pressed it twice it would write two lone accent symbols like this: ``. one day, it randomly stopped waiting for the vowel and immediately writes two symbols so it renders writing the accented letters impossible. i had changed no setting, done nothing, and my keyboard cannot be dirty or something because otherwise it would be hitting that key twice in other languages too. i cleaned it anyway. i tried redownloading the Danish layout but nothing changed. what can I do? having to change language gets quite annoying when you have to do it often.
