Every time I want to use ", ', or ` I have to hit space to type a single character. In some apps, for example VS Code, this situation is worse where I cannot even type a single character. Here is a gif that shows what I mean:

Go to System Preferences > Keyboard > Input Sources and get rid of the item called "US International PC". Instead use US or ABC.

(US International PC is a special layout where those characters are deadkeys for typing accent marks used is various European languages).
