Removing these mixins from the mod allows it to launch. ``` "vanillachanges.allowduplicatekeybindings.client.ControlsListWidgetKeyBindingEntryMixin", "vanillachanges.allowduplicatekeybindings.client.GameOptionsMixin", "vanillachanges.allowduplicatekeybindings.client.KeyBindingMixin", ```

Two mixins are at fault here: "AnvilScreenHandlerMixin" and "FillCommandMixin" Remove them by editing ledger.mixins.json, then compile the mod using gradle.
