Gnome-Tweaks «Оболочка Gnome не запущена»

Я со вчерашнего дня пытаюсь запустить и установить GNOME Tweaks но он говорит мне, что он уже существует. Но оболочка не работает:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
gnome-tweaks is already the newest version (3.34.0-3).
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

Когда я пытаюсь открыть ее вручную, я не могу ее найти.

Я пытаюсь открыть через терминал, и вот что происходит:
