Hi,

I have a notebook where the call sol0=solve(prob, alg, dt=dt, adaptive=false);  
fails with error: “No matching function wrapper was found” with 1.8.4 release but  
works correctly with 1.6.6 release.

The notebook and all details are here,

> <https://github.com/mikelehu/IRKGL_SIMD_NEW/blob/master/Experiments/J2/J2_VOP%20benchmark.ipynb>

I am confused and I would sincerely appreciate help to solve the issue

First of all: Are your packages up to date? Try going to Pkg mode (“]” in the REPL) and then “up”.

```julia
_call(#unused#::Tuple{}, arg::Tuple{VecArray{8, Float64, 2}, VecArray{8, Float64, 2}, Vector{Float64}, SIMD.Vec{8, Float64}}, fww::FunctionWrappersWrappers.FunctionWrappersWrapper{Tuple{FunctionWrappers.FunctionWrapper{Nothing, Tuple{Vector{Float64}, Vector{Float64}, Vector{Float64}, Float64}}, FunctionWrappers.FunctionWrapper{Nothing, Tuple{Vector{ForwardDiff.Dual{ForwardDiff.Tag{DiffEqBase.OrdinaryDiffEqTag, Float64}, Float64, 1}}, Vector{ForwardDiff.Dual{ForwardDiff.Tag{DiffEqBase.OrdinaryDiffEqTag, Float64}, Float64, 1}}, Vector{Float64}, Float64}}, FunctionWrappers.FunctionWrapper{Nothing, Tuple{Vector{ForwardDiff.Dual{ForwardDiff.Tag{DiffEqBase.OrdinaryDiffEqTag, Float64}, Float64, 1}}, Vector{Float64}, Vector{Float64}, ForwardDiff.Dual{ForwardDiff.Tag{DiffEqBase.OrdinaryDiffEqTag, Float64}, Float64, 1}}}, FunctionWrappers.FunctionWrapper{Nothing, Tuple{Vector{ForwardDiff.Dual{ForwardDiff.Tag{DiffEqBase.OrdinaryDiffEqTag, Float64}, Float64, 1}}, Vector{ForwardDiff.Dual{ForwardDiff.Tag{DiffEqBase.OrdinaryDiffEqTag, Float64}, Float64, 1}}, Vector{Float64}, ForwardDiff.Dual{ForwardDiff.Tag{DiffEqBase.OrdinaryDiffEqTag, Float64}, Float64, 1}}}}, false})

```

`IRKGL_SIMD.jl` needs to use `f = SciMLBase.unwrapped_f(prob.f)` in order to unwrap it and force compilation

Thanks, now the call sol0=solve(prob, alg, dt=dt, adaptive=false) does not fail.
