PS: I uninstalled performant.

Additional Information

I am trying to run halogen on valhelsia 3. The mod shows as sodium in the log. I know it has compatibility issues with Performant, another mod, so I uninstalled it. Though it still crashes. I checked the log myself but couldn't make too much out of it. One line in the log says something with "com.performant.coremod.mixin.world.StructureMixin".
