In the output one can see the seminar document class version (2014/01/17, 1.61) which the stackoverflow commenters say is too old to work with the TexLive from 2021 and should be updated to 1.63a.

The actual package delivering /usr/share/texmf-dist/tex/latex/seminar/seminar.cls is dev-texlive/texlive-latexrecommended-2021.
