There are too much client side mods there Like dynamiclightsreforged FpsReducer embeddium BetterModsButton sounddeviceoptions mousetewaks etc Maybe switch to a pre-configured modpack - most of these have a server pack - use such a modpack as working base

Add crash-reports with sites like https://paste.ee/ and paste the link to it here Looks like the server does not have access to the directory - make a test with another directory Also, use Java 17 instead of Java 18

This mod generates some kind of error/spam loop

Remove Rubidium - you are already using Embeddium which is a fork of Rubidium

There is an issue with Rubidium - try other builds or make a test without it

There is always the latest.log in the logs-folder - add this one

Try to get the crash-report or latest.log and add it here with sites like https://paste.ee/

Use a pre-configured modpack from curseforge as working base

Try other builds of these mods
