which points to https://github.com/JuliaData/Arrow.jl/blob/56f8f9342389c1b9664157ca4a2d1f5501d8341d/src/ArrowTypes/src/ArrowTypes.jl#L208

I don't have a MWE currently.

Another one. I think I'm calling copy(::DataFrame).

I wonder if JuliaLang/julia#47865 is related; the _Symbol there differs from the problematic line here by a root argument 🤔
