I made a fabric modpack and added all the mods from the modpack to the server (except client-side only or ones I couldn't find in Aternos' modlist) and for some reason it just starts and after around 30 seconds crashed while not being able to join while its started. I put the log in the files on this post. I replaced cardinal components, because searching for "dev.onyxstudios.cca.api.v3.component.ComponentContainer" gave me its Github so I thought it would just be corrupt or something.
