TileEntity

There is an issue with krypton - make a test without this mod

Do not use cracked Launchers

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

Check for CPU/GPU driver updates

Try other builds: https://www.curseforge.com/minecraft/mc-mods/littletiles/files?page=1&pageSize=20&version=1.20.1&gameVersionTypeId=1

Maybe voicechat - I am not sure

Make a test without Optifine If this is not working, add the crash-report or latest.log with sites like https://paste.ee/ and paste the link to it here

Maybe something on your system is causing the issue With installing a driver, the installer checks the compatibility with your CPU/GPU - so if the installation is working, but the system has issues after that, then it may refer to an issue with your system

This may refer to a driver issue - if you are using AMD/ATI, check their website for the latest driver build

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

Remove client-side-only mods from the server - you can keep these in your client Start with removing DynamicLights If this is still not working, add the new crash-report - use sites like https://paste.ee/ to add crash-reports and paste the link to it here

Looks like it is some kind of conflict with brutalbosses - it refers to the Reaver Remove brutalbosses or try other builds of these mods Or check the config - maybe there is a way to disable the Reaver

The server may use another ATM9 modpack build - make sure client and server modpack are the same

Make a test with another Launcher like Multimc or AT launcher

Make a test without canary

Backup and delete the config folder and test it again

There is an issue with the mod Spellblades and Such

Make a test without the mod searchables

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

Add mcjtylib: https://www.curseforge.com/minecraft/mc-mods/mcjtylib and rftools: https://www.curseforge.com/minecraft/mc-mods/rftools-base If there are still issues, also make a test without Rubidium

Maybe use a pre-configured modpack - most of these already have a server pack Use such a modpack as working base and add new mods one by one

It is an issue with Optifine Use Forge 43.2.14 (may break other mods) or replace Optifine with Rubidium + Oculus

Looks like there are client-side-only mods in your server's mods folder - add a screenshot of your server's mods folder
