Open Can't Launch Revelations at all

My buddy runs a small time revelations server for our friend group, and there is roughly 5 of us who play on said server. We have added our own mods to the modpack but nothing special, and none of us have ever encountered any issues with anything. Our other friend who was wanting to join has installed Revelations but can't seem to boot up the game he crashes and gets a crash report with - "net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from GenDustry " in it.

Here is the pastebin of the crash report-

What we have tried to fix his issue:
Reinstalled Java, vanilla Minecraft, the twitch launcher, and Revelations
Have put the ram to 10 Gb
set the launcher to JAR
installed a fresh version of chickenlib
implemented a .class file to fix the lang issues with GenDustry, and even though that solves Gendustry, another mod pops up with the same problem.

*note that the same thing was happening to him with our crackpack 3 server.

We have literally no idea how this is happening as we thought this issue was fixed years ago,
any help is appreciated thanks.
