TileEntity

And without easy villagers?

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

There is an issue with Cobblemon - try other builds

Remove terraria

Then it refers to another mod - I have no idea which one

Make a test without Curios

Add some screenshots of this setup

You will need an older Java 8 build - oracle 311 or older, azul b308 or older

I have no idea - maybe make a test with a pre-configured modpack - most of these already have a server pack - use it as working base

Did you remove the # at -Xmx4G in the user_jvm_args.txt?

Add it: https://www.curseforge.com/minecraft/mc-mods/ctm

Maybe a mod is breaking the IDs - mods like JEI or similar

Does it work without ConnectedTexturesMod?

Keep using the javaw.exe and check ingame for the server or the log in the server's logs folder

Make sure you are starting the forge jar via script

Same issue without supplementaries?

Did you set the java 17 path to the javaw.exe in your script? For example: "C:\Program Files\Java\jdk-17.0.11\bin\javaw.exe" @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.20.1-47.3.0/win_args.txt pause

Make a test without Shimmer-forge

I have no idea - maybe use a pre-configured modpack as working base and add some new mods

It is a vanilla server, not a forge server

There is no access to the log

Minecraft Version? Java Version? Maybe both versions are not matching

Same issue without ImmersivePortals?
