Been trying to update my HelloJulia.jl Pluto course to Julia 1.8 but running into problems. I can create a sys image fine. But when I call PrecompilePlutoCourse.start() it triggers a MKL artifact download (ultimately needed by Makie) which seems to timeout and then mysteriously reports that MKL is downloaded, but pluto never launches:
Downloading artifact: MKL
