MWE:

julia> Array(reinterpret(reshape, Float32, ComplexF32[1.0f0+2.0f0*im]))
ERROR: MethodError: no method matching isassigned(::Base.ReinterpretArray{Float32, 2, ComplexF32, Vector{ComplexF32}, true}, ::Base.SCartesianIndex2{2})

Closest candidates are:
  isassigned(::AbstractArray, ::CartesianIndex)
   @ Base multidimensional.jl:1568
  isassigned(::AbstractArray, ::Union{Integer, CartesianIndex}...)
   @ Base multidimensional.jl:1569

Also noticed in the ImageCore tests with isassigned(::ReinterpretArray, ::Base.SCartesianIndex2{2}). xref https://github.com/JuliaImages/ImageCore.jl/actions/runs/7655272073/job/20860957804?pr=199
