Hi all!
I wonder if you can help me here with something Julia and VSC related
I used to work with Atom as a Julia IDE. Now that Atom is gone, I hear everyone is using VSC.
In my clean new s MAC OS system I installed Julia 1.9 beta (downloaded the .dmg, moved the file to Applications, and added the bin to the tcsh path).
I installed VSC and downloaded the Julia package, and put the path to the bin.
I keep getting this messages:
and the next log output:

As per the first link, try switching to a pre-release version of the VSCode extension.
