Well, the server wasn't generating any logs, so I had nothing to send you, HOWEVER I managed to fix every issue by downgrading my Java from 20 to 17, and the reason why nothing was working was simply due to me not properly uninstalling Java 20, causing an association error.
So, it turns out I needed to downgrade Java from 20 to 17, and while I did do that and it stopped the errors, now I can't run the server or even play minecraft in general (singleplayer). Um, help?
Update, I found out, it was the create mod, a mod called "mystical oak tree", and the carpeted mod that were causing the errors. However, I would really love to keep these, especially the create mod, is there any way to fix these errors without removing the mods?
