1.12.2 having trouble getting the server to start

[plz help brain hurt]

So I'm trying to run an RLCraft on the Ubuntu server version, created mods file but when I try to use run.sh I get: 

Exception in thread "main" java.lang.IllegalArgumentException: kotlin.native.concurrent: Invalid package name: 'native' is not a Java identifier
       

The current version of Java I have installed is:

OpenJDK version "17.0.10" 2024-01-16
OpenJDK Runtime Environment (build 17.0.10+7-Ubuntu-122.04.1)
OpenJDK 64-Bit Server VM (build 17.0.10+7-Ubuntu-122.04.1, mixed mode, sharing)

I tried to manually input all of the RLCrafts files for the zipped server download by just unzipping and putting them into their dedicated places. EX: I removed the created mods file, then implemented it back in with all of the RLCrafts mods along with config. Then I added the stuff that was missing, like resource packs and resources 

the forge version I installed for the server was I think 1.20.2 or something like that I downloaded the recommend one 

 

This is my first time doing this plz help brain hurts

Hey, buddy. Let's check what we can do  First, make sure you are using a compatible version of Forge to run RLCraft on your server. This can help avoid unexpected problems.
Also try reaching out to the RLCraft community or mod developers for help. Perhaps other users have encountered a similar problem and can share their experience or solution. And tell me, if this won't help you!

RLCraft is a 1.12.2 modpack

So you will need Java 8 to run this modpack

There is already a serverpack - at Additional Files, download the Server Pack - so you don't need to install Forge separately
