error with loading the jld file containg the reture value of Optim.optimize

I am using Julia 1.6.1, JLD v0.12.3, Optim v1.3.0 The reture value of Optim.optimize is saved in the "res.jld" file, while loading this file, I got the following error:

julia> res = JLD.load("res.jld"); error parsing type string Optim.MultivariateOptimizationResults{Optim.LBFGS{Core.Nothing,LineSearches.InitialStatic{Core.Float64},LineSearches.HagerZhang{Core.Float64,Base.RefValue{Core.Bool}},Optim.#17#19},Core.Float64,Core.Array{Base.Complex{Core.Float64},3},Core.Float64,Core.Float64,Core.Array{Optim.OptimizationState{Core.Float64,Optim.LBFGS{Core.Nothing,LineSearches.InitialStatic{Core.Float64},LineSearches.HagerZhang{Core.Float64,Base.RefValue{Core.Bool}},Optim.#17#19}},1},Core.Bool,Core.NamedTuple{(:f_limit_reached, :g_limit_reached, :h_limit_reached, :time_limit, :callback, :f_increased),Core.Tuple{Core.Bool,Core.Bool,Core.Bool,Core.Bool,Core.Bool,Core.Bool}}} Error encountered while load FileIO.File{FileIO.DataFormat{:JLD}, String}("res.jld").
