I’m experimenting with building my Julia application into an executable using PackageCompiler.jl. The build process seems to go just fine, but when I run the executable, it tries twice to “download artifact: MKL”, appears to succeed, then hard-crashes with the message “Unable to automatically install ‘MKL’ from ‘C:\Users\manni.julia\packages\MKL\_jll\kG4RZ\Artifacts.toml’”.

I’m using Julia 1.7.2.

Here is the log from calling `PackageCompiler.create_app()`:

```julia

  ├── CImGui_jll - 3.571 MiB

  Total artifact file size: 421.233 MiB
✔ [04m:32s] PackageCompiler: compiling incremental system image

```

And the output when running the executable:"
