I got the error only after I enabled the hyphenation patters. This
indicates that the problem are not spaces but hyphenation. The
documentation of soul says that "Reconstruction failed" means that
soul gots confused about the width of the sylables. The width is
measured by the width of -. So this need to be set too. So

\makeatletter
\font\SOUL at tt="FreeMono-Normal"
\setbox\z@\hbox{\SOUL at tt-}
\SOUL at ttwidth\wd\z@
\makeatother
 
should do the job (I had to use another font for testing.)

(And the second \makeatletter in my first posting was naturally
simply a typo.)
