Any command results in Traceback

[WatermelonDriveway]

Can't seem to get beets to do anything after a system restore. Any command leads to the same traceback error. Plugins disabled, reinstalled python, pip, and beets. Not sure what I could be doing wrong here.

library: ~/.beets/musiclibrary.blb

original_date: yes


paths:
   default: $albumartist/($original_year) $album/$track - $title
   comp: Various Artists/($original_year) $album/$track - $title

import:
   timid: no
   write: yes
   per_disc_numbering: yes
