Brave Browser (Snap) не запустится - возможно, связанный с AppArmor

Установлен Brave (snap) через Центр программного обеспечения в Ubuntu 18.04. Кажется, правильно установить. Когда я нажимаю на запуск, ничего не происходит, но в журнале полно сообщений об устройствах.

Я прикрепил журнал внизу. Любые идеи о том, как я могу это исправить?
