Game wont launch

I'm trying to play a Minecolonies modpack, and when I go to launch it it, it shows the Mojang loading screen, before returning to the launcher and giving me this error:

The game crashed whilst rendering overlay Error: java.lang.IllegalAccessError: class ovh.corail.tombstone.perk.PerkRegistry tried to access method 'net.minecraftforge.registries.IForgeRegistry net.minecraftforge.registries.RegistryBuilder.create()' (ovh.corail.tombstone.perk.PerkRegistry is in module [email protected] of loader 'TRANSFORMER' @474821de; net.minecraftforge.registries.RegistryBuilder is in module [email protected] of loader 'TRANSFORMER' @474821de) Exit Code: -1

I've tried some tips from people having somewhat similar problems, but nothing has worked.

Here is the crash log: https://www.toptal.com/developers/hastebin/redomocaso.properties

Here is the debug: https://www.toptal.com/developers/hastebin/koqewoyumi.yaml

Idk if I did that right, so just tell me if i didn't and I'll fix it.

Thanks!
