Description

Is there anything that I can do to help fix https://discourse.julialang.org/t/error-with-bunchkaufman-factorization-in-turing-jl/88174 ?

I don't have experience with the forward-diff functionality. I am a Turing.jl user who encountered this error about the missing method basically.

Research direction

Start by reading the linked Discourse report about the Bunch-Kaufman factorization error in Turing.jl, then inspect ForwardDiff.jl's forward-diff functionality around the missing method. Determine the minimal reproducible failure and identify what behavior should be covered before deciding whether a fix or regression test is needed.
