Ah, your original report suggested that you did
`(set-register ?s '(file . "~/.config/fish/"))` directly.

Yes, no doubt something you are loading or doing is interfering.
The best approach for this, even before debugging to see what goes
wrong, is to bisect your init file to find the code that introduces
the problem.  This is very quick to do - it's a binary search.  Just
inhibit half of your init file, then 3/4, then 7/8, etc. until you 
find exactly where the problem is.

I haven't, but perhaps someone else here has.
