TileEntity

Remove supplementaries or try older 1.20.1 builds

And without the mod werewolves?

Add the latets.log from your logs-folder Add the log with sites like https://mclo.gs/

It is an issue with medieval_craft The error refers to "Duplicate stat id" which is common for mcreator mods Looks like it refers to an Archer - so an invalid Entity near your location Backup the world and remove this mod

It is an issue with brewincompatdelight Add this mod: https://legacy.curseforge.com/minecraft/mc-mods/collectors-reap/files/5482850

Add crash-reports with sites like https://mclo.gs/ Update CyclopsCore to this build: https://www.curseforge.com/minecraft/mc-mods/cyclops-core/files/6199446

mclo.gs only shows 25000 lines - add the rest with another link

Also add the latest.log from your logs folder

Add the crash-report

Remove canary or servercore

Make a test with Forge only - without any mods Or use a pre-configured modpack as working base and add new mods one by one

Same issue without the mod jukeboxfix?

Add crash-reports with sites like https://mclo.gs/ Remove randompatches

Looks like an issue with The_Graveyard - maybe a conflict with supplementaries Make a test without one of these mods

Did you work with Worldedit before the crash? If yes, set max-tick-time to -1 in your server.properties If not, make a test without this mod

It is an issue with chimes

I have no idea

Remove simplysneak

Try older builds of it https://www.curseforge.com/minecraft/mc-mods/fusion-connected-textures/files/all?page=1&pageSize=20&version=1.20.1&gameVersionTypeId=1

Make a test without the mod Fusion

Nothing mentioned - I think there should be a line with <player> joined the world or similar

Also make a test without butcher

Looks like some kind of mod mismatch error But also make a test without fancymenu, modernfix and nochatreports

And without jeresources?

Make sure you add the log after testing it
