1.19.2 Server crashes SOMETIMES on startup with "Failed to create mod instance"

[Joni97]

Hello,

I just joined your wonderful forum for a problem, I'm currently assembling a modpack to play for on my root server, I used a bigger modpack and modified it, throwing mods out and putting some new in.

Unfortunately, I'm encountering a weird error, sometimes the server crashes on startup bc of a few mods(not every time the same ones) throwing “Failed to create mod instance”.

At the final error message, the mods which failed to load get listed with:

Spoiler

"[main/ERROR] [net.minecraft.server.Main/FATAL]: Failed to start the minecraft server

net.minecraftforge.fml.LoadingFailedException: Loading errors encountered: [

  Mekanism (mekanism) has failed to load correctly

§7java.lang.reflect.InvocationTargetException: null,

  RFToolsControl (rftoolscontrol) has failed to load correctly

§7java.lang.reflect.InvocationTargetException: null

]"

Thanks in advance!

PS: @diesieben07 Du machst echt gute Arbeit, bei jedem Problem auf diesem Forum sehe ich dich mit den einfachsten Antworten , danke. (sorry for german lang)

Looks like every mod has the same error: "Exception message: java.util.ConcurrentModificationException"
