wimlib

How do I resolve this so I can proceed?

I am attempting to do this on an M1 MacBook Air (not Intel) and am following an online post leading me through this. But ran into the unanticipated error noted above. Here is the how to article I am using https://www.makeuseof.com/tag/bootable-windows-10-mac/

This sounds like an issue with Homebrew and not with wimlib upstream.
