Issue Launching Modded Server

[MajoraGuy]

Trying to get a server set up for a moderately-sized group of people, but encountering significant resistance where I've never really had an issue with forge modding before. It's a sizeable modlist, but I found when testing even just 2 mods, the whole thing crashes.

Mod List:

 

Debug Log (With these mods)

Debug Log (Just 2 mods)

Of note, EVERYTHING works in singleplayer, so I'm not sure why this issue is server-specific

Mixin doesn't like that you are using java 19 which was only released last week. 🙂 

Use java 17 which is the current LTS (long term support) version.

Awesome, thank you so much for the swift repsonse. I was messing around with this yesterday and had both 17 and 19, and uninstalled 17 by mistake haha. Looks like everything is working properly now! I really appreciate the support
