Hi All 🙂

I run into a very wired error. It only happens while using Julia as system-user on Windows.

Let me explain what I’m doing:  
1.) Created an project with the following structure:  
/my\_project  
/my\_project/start.jl  
/my\_project/Project.toml  
/my\_project/src/MyProject.jl

The following lines are in `start.jl`:

```julia
using Pkg
Pkg.activate(@ __DIR__ )
Pkg.instantiate()

```

2.) Start Julia REPL as “nt authority\system”:  
Here I use “PSTools”.

```julia
cmd> PsExec64.exe -s -i julia

```

Now I can see if I’m “nt authority\system”

```julia
julia>;
shell> whoami
nt authority\system

```

3.) Include the `start.jl` file:  
After that the following error occurs

```julia

```

Can anybody reproduce that error? How can I fix it?
