Here's the crash log. It started happening with the latest update:
https://paste.dimdev.org/cujavehugi.mccrash

Removed Aether Legacy, now it's Earthworks:
https://paste.dimdev.org/awejezigiy.mccrash

Removing both mods stops the issue from happening

Thanks for reporting this, there should be a fixed version at https://www.curseforge.com/minecraft/mc-mods/thaumic-augmentation/files/2741499
