Hi @KMACEL
the problem is upstream, I think you might have this same issue as golang/go#32495 where you might have accidentally go get the wrong version of https://github.com/russross/blackfriday.

I've opened #284 to consolidate the mod state but at glance it won't help you if you have blackfriday v2 installed. Can you try again from a clean state and let us know if things are different with these new info?

I'm closing since this seems to work now, feel free to reopen if you still have the issue

There's a problem with [email protected]/md2man library. I have also found this in different projects, hope is solved soon.
