if your steam is a flatpak package you need to change the following lines:
${HOME}/.steam/root/steamapps/libraryfolders.vdf to "${HOME}/.steam/data/Steam/steamapps/libraryfolders.vdf"
$HOME/.steam/steam/steamapps/libraryfolders.vdf to $HOME/.steam/data/Steam/steamapps/libraryfolders.vdf
$HOME/.steam/steam/config/libraryfolders.vdf to $HOME/.steam/data/Steam/config/libraryfolders.vdf
