I hinted at the potential for problems the "\" in the string, and it looks like you may have hit that. Microsoft have a lot to answer for in choosing to use a backslash as the directory delimiter - it has cost man-years of effort in people having to unravel it (including within Microsoft, as they use C and its derivatives for development).
It is possible that the behaviour will differ depending upon whether you use the command in a script or at the command line, and whether you use single or double quotes.

I don't see why the command should've hung, so it just might be worth checking that you have matched up the pairs of single and double-quotes on the revised command.

It looks to me like you're trying find a line with a DOS path on it (grep 'L:\\\:' is looking for a string L:\:) and then strip off the path to leave the filename (sed -e 's/.*\\\//' means delete everything up to the last backslash).
If that is the case, then you might try replacing the hard-wired grep with an extended grep egrep '[A-Z]:\\\:'.

What's the output of the "subst" command alone?
And what would you like the result to look like?

Using eval is going to add in even more dependencies on the backslashes.

Incidentally, are you sure it's the right number of backslashes and : characters in your string?

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
