MWE:

julia> using Optim, Enzyme, LinearAlgebra

julia> function f(x)
                  y1 = zeros(eltype(x), 3)
                  y2 = ones(eltype(x), 3)
                  y1 .+= (3 - sin(x[1]))^2
                  y2 .+= (x[2] - 3)^4
                  dot(y1, y2)
              end

Are you sure this is not an Enzyme problem? It seems to refer to the Enzyme.Compiler. I don't know much about their project unfortunately.
