Hi Nicolas,
`guix install texlive-scheme-basic` helped in my case.
Output of `guix package --export-manifest` after above command:
(specifications->manifest
(list "ytfzf"
"emacs-ytdl"
"emacs-org-caldav"
"mpv"
"youtube-dl"
"emacs"
"texlive"
"emacs-elfeed-org"
"emacs-org-contrib"
"emacs-ledger-mode"
"ledger"
"emacs-debbugs"
"texlive-wrapfig"
"texlive-scheme-basic"
"emacs-vterm"
"font-fira-code"
"emacs-elfeed"
"glibc-locales"))
