This is a log from a server on apex so custom.jar is fabric
originally thought to be an issue with an incompatibility between fabrication and carpet but both said it was cardinal components

Hmm no it does seem like the issue comes from a carpet mixin. I don't see how CCA could be responsible for a mixin failure.
