you need to downgrade to Java 8 from Java 17 [15:08:58] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher 8.1.3+8.1.3+main-8.1.x.c94d18ec starting: java version 17.0.6 by Oracle Corporation Its using Java 17 after this it should be working!

If you are playing on a server that you can open with a run.bat then you can go through a tutorial that way, however if it is one that you host and play through LAN then I am unsure.

Disregard my previous Post Its your Java conflicting with one another Make sure ONLY JAVA 17 is installed Message me if you need more help

For anyone having problems in the future, It was Java conflicting with the older version of minecraft, for 1.18.2 you need to uninstall java 18 or 19 from Windows-->Settings--->Apps and Data---> find Java 19 and uninstall it and then install java 17 Fixed the problem immediately Was hard to find a solution online so I hope this helps

Is it a server or private minecraft world? You also should be able to find it in a crash reports

JEI is causing it Could be an outdated version with the modpack or one that is to modern for the earlier Minecraft version Make sure the compatibility mods/ mod library mods are installed! Message me if you have any further questions

Your first initial Error has to do with the .bat file It may not be reading past the .bat into the server at all and crashing on the spot instead Feel free to message me, ill get back as soon as possible

You can always do a new server file, just create a backup and copy it over to the new server Or you can try setting the world spawn in a different place by using a command in game also what version is your server on? 1.18.2? 1.19.2?

Try to reinstall Java, usually fixes the "Remove FoamFixAPI" If not send a message, Ill do my best to help/respond

Disable flight in server config/data an outdated java might be the case on a newer java server as well Try both out and see if it works!

limit yourself to 1 big mod and maybe 8-10 smaller ones, any Version will do

Is the best option to completely uninstall Java 19 and install java 17? Or is there a way to change it from 19 to java 17 through the .bat? Thanks!

The Mods are conflicting with one another, try giving one priority over the other, or find a compatibility mod to go with let me know if this helps

Have you tried Allocating more RAM? it might be the server trying to load in the chunks however it can only go so fast Its not your Internet or connectivity you can also try having their render distance lowered to 2 or 1 chunks instead of 12 Goodluck
