Sounds a lot like my first to days of trying to open games on linux (I am on Manjaro with KDE Plasma). I missed to create a swap partition and my RAM couldn’t handle some games that just didn’t start or closed after a few minutes. Maybe that’s your problem as well.

A word is hyphenated if it is written with a hyphen, i.e. ‘-’. So the joke is the word hypenated is not hyphenated, so non-hyphenated, while the word non-hyphenated is hyphenated.
