Are you 1.18.2, if so you must change to 1.17, due to the fact that Skript's 1.18.2 has not officially been updated by Minehut, and if you were to use it, you must download it from the github, link is here: https://github.com/SkriptLang/Skript/releases that will be the only way to get it 1.18.2, otherwise you have no other answer.
