My video.scm already has libass. I tried removing and reinstalling VLC but it doesn't work.
 Am I missing something?

It seems that our vlc package lacks libass as an input:

  https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/video.scm#n810

Could you try adding libass in the vlc package definition, then install
it, and see if it works?

If you’re not familiar with Guix packaging, see
<https://www.gnu.org/software/guix/manual/html_node/Defining-Packages.html>,
and do not hesitate to ask for guidance here or on #guix on IRC!

HTH,
Ludo’.
