Problematic install of babel-scottish

Question

Here are two failed attempts to install the downloaded (by MiKTeX) files for babel-scottish. It seems to revolve around the missing file hilatex-dev.fmt presumably needed for XeLaTeX. The internet seems strangely quiet if you attempt a search for this file, so I am at a loss to solve the update formats problem. There doesn't seem to be the necessary update button in the MikTeX Console to rebuild the language database. What should I try next?

C:\Users\hsmye>miktex --enable-installer formats build

Sorry, but: Windows API error 2: The system cannot find the file specified.

Sorry about the length; this is as close to an MWE as I can get.

BTW, have you ever seen a Windows install that buchered a user name? Notice the user name in the log files…

Almost forgot, here is the warning in a run with XeLaTeX

Sorry about the formatting of the message, but this is what a 'copy' returns.

New information, this is from my current run

It clearly knows about the necessary files but can't seem to get to them. I've filed a bug report in GitHub with MikTeX.
