The underlying code in the package LWFBrook90.jl simplifies to the following MWE:

using ComponentArrays # version: [b0b7db55] ComponentArrays v0.15.2
u0 = ComponentArray(
    GWAT   = (mm = 0.0, d18O = 0.0, d2H = 0.0),
    INTS   = (mm = 0.0, d18O = 0.0, d2H = 0.0),
    INTR   = (mm = 0.0, d18O = 0.0, d2H = 0.0),
    accum  = (cum_d_prec = 0.0, ))
reduce(vcat, [u0.GWAT.mm, u0.INTS.mm, u0.INTR.mm])           # works
reduce(vcat, [u0.GWAT.mm, u0.INTS.mm, u0.INTR.mm, u0.accum]) # doesn't work

giving the error:

julia> reduce(vcat, [u0.GWAT.mm, u0.INTS.mm, u0.INTR.mm, u0.accum]) # doesn't work
ERROR: MethodError: vcat(::Vector{Float64}, ::ComponentVector{Float64, SubArray{Float64, 1, Vector{Float64}, Tuple{UnitRange{Int64}}, true}, Tuple{Axis{(cum_d_prec = 1,)}}}) is ambiguous.

Candidates:
  vcat(x::AbstractVector, y::ComponentVector)
    @ ComponentArrays ~/.julia/packages/ComponentArrays/NnCVQ/src/array_interface.jl:37
  vcat(X::Union{Number, AbstractVecOrMat{<:Number}}...)
    @ SparseArrays ~/.julia/juliaup/julia-1.10.0-beta2+0.x64.apple.darwin14/share/julia/stdlib/v1.10/SparseArrays/src/sparsevector.jl:1229

Possible fix, define
  vcat(::AbstractVector{<:Number}, ::ComponentVector{<:Number})

Stacktrace:

the vcat in v1.10 is breaking ReverseDiff too.
