Hi, i have encountered this issue.

Modpack: TechAcademy 0.7.2 + some custom mods
Minecraft version: 1.21.1
Apotheosis version: Apotheosis-1.21.1-8.1.3
Neoforge: 21.1.115

This is an issue between Architectury and NeoForge, nothing to do with apoth.

To anyone who is looking for a solution to this error:
Apotheosis and Architecture API alone do not conflict with each other. The problem is caused by other mods that the log does not show. If you encounter this error and are developing your modpack, I recommend running the game, adding one mod at a time to identify the one causing the problem. In my case was by Mining Utility.
