Code running on local Julia, but failing on CI tests with Ububtu_latest and Windows_latest

[andreasvarga]

The following code is running correctly on my machine

using LinearAlgebra
using ApproxFun
Af = Fun(t -> [0 1; -10*cos(t) -24-10*sin(t)],Fourier(0..2π));
D = Derivative(domain(Af));
ND = [D 0I; 0I D];
Aop = Af - ND;
NA = 322
RW = Aop[1:NA,1:NA]

resulting in a matrix as below

322×322 ApproxFunBase.RaggedMatrix{Float64}:

However, the same sequence fails on the Ubuntu_latest and Windows_latest CI test environments with both Julia 1.7.2 and Julia 1.8.0
with the following message

ERROR: LoadError: MethodError: no method matching blocks(::ApproxFunBase.InterlaceOperator{Float64, 2, ApproxFunBase.ArraySpace{ApproxFunBase.SumSpace{Tuple{ApproxFunFourier.CosSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunFourier.SinSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}}, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, 1, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunBase.ArraySpace{ApproxFunBase.SumSpace{Tuple{ApproxFunFourier.CosSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunFourier.SinSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}}, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, 1, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunBase.CachedIterator{Tuple{Int64, Int64}, ApproxFunBase.BlockInterlacer{Tuple{FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}, FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}}}}, ApproxFunBase.CachedIterator{Tuple{Int64, Int64}, ApproxFunBase.BlockInterlacer{Tuple{FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}, FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}}}}, Tuple{Infinities.RealInfinity, Infinities.InfiniteCardinal{0}}})
(see run information here)

I would appreciate any hint how to manage to run the tests without this error.
