I can't replicate that, but I do get jekyll/jekyll#8523 which I'll make a PR to fix.

Even after webrick is installed, I still got the same

Ok, I was able to reproduce on Debian. Someone else had the same problem. Full stack trace below. The cause isn't obvious to me, but presumably a jekyll issue that can't be fixed in this repo.

Ah, it's a common (and planned) ruby 3 issue, should've spotted that. The fix is in pathutil at envygeeks/pathutil#5 so this will persist (on platforms where pathutil uses that particular code) until that gem gets updated.

The version of Jekyll being used by GitHub Pages no longer uses pathutil envygeeks/pathutil#5 (comment)
