TileEntity

Make a test just with Forge - if this works, add the mods one by one or in groups until you find the one causing this issue

Is there a crash-report or log? If yes, add it with https://mclo.gs/

Update your AMD/ATI drivers - get the drivers from their website - do not update via system

Try both

This refers to the llibrary issue Replace llibrary and jurassicraft with the unofficial updates from the latest comments: https://github.com/iLexiconn/LLibrary/issues/200

I have no idea - maybe reinstall this modpack or try another build of it

And rltweaker?

Does it work without Create and its add-ons?

Add crash-reports with sites like https://mclo.gs/ It looks like Pehkui is conflicting with nethersdelight - make a test without nethersdelight

Make a test without illagersweararmor

And without sereneseasons?

Replace it with this build: https://www.curseforge.com/minecraft/mc-mods/better-dogs-x-doggy-talents-next/files/4971380

Temporary remove blockoverlayfix

Add crash-reports with sites like https://mclo.gs/ It is a conflict with ldlib - try other builds or remove it and the mods requiring it

Make a test without essential or test it with adding kotlin https://www.curseforge.com/minecraft/mc-mods/kotlin-for-forge

Add crash-reports with sites like https://mclo.gs/ Delete the config file eidolon/dark_prayer.toml

Make a test without the xaero mods, supplementaries and modernfix

Same issue without valkyrienskies?

Remove client-side only mods from your server Add a screenshot of your mods folder

Add crash-reports with sites like https://mclo.gs/ Delete the json file at \.minecraft\config\byg\trades.json5

Also add the latest.log from your logs-folder

Add the new latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

Use Java 17

If other build do not work either, report it to the creator

Maybe an issue with spawnstructures_forge
