@Pangoraw what do you think about the failing tests?

[Pangoraw]

I changed the test because the LOAD_PATH is different when in testing and I did not understand how the LOAD_PATH is propagated to the worker depending on the version.

Ahh this is because of a change in Distributed in Julia 1.9:

https://docs.julialang.org/en/v1/NEWS/#Distributed

In Malt we never propagate the value, and Malt is enabled by default on Windows only right now.

oooh that makes sense, i changed the test but it may be relying on somehow passing the environment. The fix is working though.
