Hello, I was using JuliaPro v1.4.0 on Windows 10. I was trying to install a package but the REPL got stuck so I interrupted it. Since then I’m no longer able to install any package due to this error. Did I break something? Is there a any way to fix it?

I actually switched to vanilla Julia + Atom. But I believe if you just reinstall latest version JuliaPro that will also do.

I reinstalled what ends up being one version up, 1.4.2-1, and that resolved the problem.

I can resolve by desinstalling Julia, erase the folder .julia (C:\Users\HP.julia in my case) and re installing
