The version of tar provided by Cygwin is GNU tar, and according to https://www.gnu.org/software/tar/manual/tar.html#Synopsis, an exit value of 2 means some fatal, unrecoverable error occured.
The recommended way on Windows is to use the builtin cygwin instead of your own. Could you try again after removing C:/Users/שזדס/AppData/Local/opam and trying again with the default opam init (you can add --cygwin-internal-install to make sure you're using the right one but in theory it should be the default)
Tried running opam init --cygwin-internal-install, but I was unable to click on ANYTHING in the Cygwin setup window
The setup is automatic, this is expected. Was the setup window frozen or doing something? It's supposed to close by itself once everything is done

The window was indeed frozen. If it helps, here's the window in question:
arf, i was able to reproduce. On a windows account without any UTF8 characters it works without issues but on a windows account with UTF8 characters setup.exe freezes the same way.
I'm not sure where the issue is yet but it could be a bug in cygwin's setup.exe project, or maybe it's a bug in how we call it.
