The only issue that I've found similar to what you have is this one: https://www.reddit.com/r/osugame/comments/bny93r/cant_install_game_anymore/.
Can you open up Font Book (open spotlight and search for Font Book) and then see if there's any font with the name of Aller or Aller Light and then right click it and click "Remove" (or if that option is greyed out, click "Disable").
