New ReconstructedTypes issue

My package loads a data type from file using JLD2

@load joinpath(@__DIR__,"exactcore.jld2") ψi

where the type is

`Interpolations.GriddedInterpolation{Float64, 1, Float64, Interpolations.Gridded{Interpolations.Linear}, Tuple{Vector{Float64}}}`

I don't export the Interpolation, but I do export a function that uses it. Previously this worked fine.

Recently I get a new error:
```
┌ Warning: saved type Interpolations.GriddedInterpolation{Float64, 1, Float64, Interpolations.Gridded{Interpolations.Linear}, Tuple{Vector{Float64}}} is missing field it in workspace type; reconstructing
└ @ JLD2 ~/.julia/packages/JLD2/JlkeJ/src/data/reconstructing_datatypes.jl:152
ERROR: LoadError: Evaluation into the closed module `ReconstructedTypes` breaks incremental compilation because the side effects will not be permanent. This is likely due to some other module mutating `ReconstructedTypes` with `eval` during precompilation - don't do this.
```

If I wind back to `Interpolations v0.13.2` then it works fine.

Is there a breaking change I need to know about?

Is there a better way to do this? or a generic fix?

Thanks
