I saw this topic Browser don't work - #6 by Guillaume and tried launch Brave from the terminal. This is what I got:
user1@laptop:~$ flatpak run com.brave.Browser
Gtk-Message: 18:44:46.884: Failed to load module "canberra-gtk-module"
Gtk-Message: 18:44:46.889: Failed to load module "canberra-gtk-module"
Assertion 'p' failed at src/libsystemd/sd-event/sd-event.c:178, function event_origin_changed(). Aborting.
Could the canberra-gtk-module have anything to do with my issue? If so, should I install it? If so, is the best way to that sudo apt install canberra-gtk-module?
