Nautilus refuses to open on command, even as sudo.

[Jeb E.]

See the bug on GNOME's Gitlab here--> https://gitlab.gnome.org/GNOME/nautilus/issues/172

ISSUE:

Clicking on the "Files" (default file manager) app in Ubuntu is not resulting in Nautilus opening a new window, not even a new tab or session.
Opening a System Monitor session does not show that Nautilus is running, either.

Nautilus also refuses to open via Terminal as myself *or* sudo.

TERMINAL OUTPUT:
"
jeb@Inspiron13:~$ nautilus
sys:1: PyGIWarning: Nautilus was imported without specifying a version first. Use gi.require_version('Nautilus', '3.0') before import to ensure that the right version gets loaded.
No module named requests
jeb@Inspiron13:~$ sudo nautilus
