Minecraft crashes on servers when doing simple things like changing your hand item, walking and loading chunks, turning your screen, etc. It's mainly lag related, meaning the worse the lag the worse it'll get, but it didn't happen before 1.20.30 so it's safe to say it's a bug.

The Hive freezes less than my personal server, it uses geyser but I didn't update geyser or the server before this started happening, it started when I updated to 1.20.30. Using a Moto G6 plus.
