Crash Due To Unknown Mod

While I'm looking at the log, please tell the story in plain English about what is going on.

I start the server, it crashes. I recently updated the server, both NeoForge and mods. Some client mods are inside and I am slowly picking them out as we speak. I don't know what else to add here.

updated the server, meaning it worked before without issue?

mmm not good

Correct

updating your server jar to a newer version is typically handy, but its a tedious process as mods need to be updated to X neo version to run right

what's the modpack

the mod list is right here

custom modpack i assume

it's all custom so

yeah

custom, got it

and the mr pack only has client information so I have to manually update the mods for the server yada yada

ive been seeing too many of these

 net.neoforged.neoforge.common.NeoForgeMod$$Lambda/0x00007fcfdcd4ad08@7eb9a65c

its something to do with the world being fucked and wanting to be launched in safe mode too

I would hope the world isn't fucked goddamn 😭

I mean there are mods adding ores and tectonic is in there etc
