Yes - use 1.20.4

Check for worldedit ingame Make sure you are using 1.20.4 or older - for 1.20.5 or newer there is no build https://www.curseforge.com/minecraft/mc-mods/worldedit/files/all?page=1&pageSize=20&version=1.20.4&gameVersionTypeId=1

If you are using AMD/ATI, update your drivers - get the drivers from their website - do not update via system

Maybe an issue with alexsmobs

Did you get the latest drivers from their website? Do not update via system

Also add the latest.log

Is there a crash-report?

Check the worldsave \saves\WorldSave\serverconfig

And without modernfix?

Get the latest AMD/ATI drivers from their website - do not update via system

There is an issue with drippyloadingscreen Try other builds or remove it

Delete the journeymap-server.toml file in your config folder if there is no change, add the new crash-report with https://paste.ee/ Maybe there are some more files broken

Maybe switch to another build of this modpack or contact the modpack owner

Make a test without crittersandcompanions

Add the crash-report or latest.log (logs-folder) with sites like https://paste.ee/ and paste the link to it here

It is an issue with changedplus

Make a test without Optifine If this works, replace it with Embeddium + Oculus

Add the full crash-report or latest.log (logs-folder) with sites like https://paste.ee/ and paste the link to it here

Get the latest AMD/ATI drivers from their website - do not update via system

Remove rubidium - you are already using embeddium, which is a fork of it

I have no idea - maybe something outside of Minecraft like Firewall or Antivirus program

First a test without it

Maybe an issue with fancymenu

Maybe an issue with Xaeros_Minimap

Looks like an issue with betterpingdisplay - make a test without it
