Space button gets stuck physically

Space button gets stuck while typing, doesn’t respond when I press on the sides of the button and it is very tight when I press at the middle of it, have to press really hard. I removed the cap of the button to see if something got under it, but it is clean and nothing is broken.

Really annoys me as laptop is just 4 months old.
