Mod conflicts

Mod 'architectury' is not available! (IllegalStateException)

What the log looks like

java\.lang\.IllegalStateException: Mod 'architectury' is not available!
dev\.architectury\.platform\.hooks\.EventBusesHooks\.lambda\$whenAvailable\$0

How to fix it

  1. Check your `mods` folder (or crash report mod list) for `omega-config` / `omegaconfig` and remove it along with any mods that depend on it, as Architectury maintainers have confirmed it misuses the API on NeoForge 1.21.
  2. If you do not have OmegaConfig installed, open the crash report and look just below the `dev.architectury.networking.NetworkManager` lines in the stack trace to find which mod or Mixin handler (`handler$...$modid$...`) triggered the call.
  3. Update the offending mod and Architectury API to their latest versions for your exact mod loader, or remove the offending mod until its author fixes its NeoForge lifecycle registration.
