Ubuntu 21.04 - Программное обеспечение Ubuntu не открывается

Вчера Ubuntu Software работала, а сегодня нет. Бег snap-storeпоказывает следующую ошибку

      /snap/snap-store/518/usr/bin/snap-store: symbol lookup error: /snap/snap-store/518/gnome-platform/usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined symbol: atk_plug_set_child

Эти два обновления произошли с тех пор, как он работал в последний раз (вчера, когда я установил Spotify).
