essentals problem. Dont use that mod anyways, it got ingame purchases and this bug is 100% their fault for fucking up mod added datapack registries

oh and btw there is no such thing as "payed multiplayer". You can play online any time, just open lan, get a vpn pogram and let your friend conect. alternatively run a local dedicated server on your machine.
If you really need a mod to makeit easier use e4mc.
using essentials is a rookie mistake

Ensure Version Loader is correct. it was 1.21-forge and the information is saying it's 1.20.1-forge

if your minecraft crashed. you need to add Crash-report and latest.log
