TileEntity

Same issue without aquamirae?

Same issue with a new world?

Still a client side only mod Remove mods one by one or in groups until you find it Or start without any mods and add the mods in groups

And remove EnchantmentDescriptions and journeymap from the server

So just add it

Did you also add CreativeCore?

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

There are more client side only mods - add a new screenshot from your server's mods folder

You can use external sits like imgBB or similar

just test it - or make a test without this mod - backup the world before

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
