Mods: Zenith (and dependencies, attributes and fakerlib), DashLoader, and Fabric api
MC Log: https://mclo.gs/JJd01jX

DashLoader has many other compatibility issues and is no longer being developed, I would personally just recommend removing it.

Edit: Case in point (actually the cause here), and marked as wontfix by Porting Lib:

Fabricators-of-Create/Porting-Lib#73
Fabricators-of-Create/Create#1412

Yeah, won't add compat for a discontinued mod.
