Skript does not currently support 1.21. It will be coming in 2.9 (next month). You can download the nightly build from here: https://github.com/SkriptLang/Skript/actions/runs/9702144977. While others have reported it to be stable, we do not recommend using it on a production server and using it is at your own risk.
