Thus looking for a support here. If there is more appropriate place to look for support in that matter please let me know.
Brave installed from snap was running perfectly fine for months.
Since two days it is not starting when clicking Brave icon from launcher.
When attempting to run Brave from command line just calling brave I am getting following warnings, browser starts but without all my profile data (bookmarks, configuration, history), and it is in unsafe --no-sandbox modee.
main.go:224: cannot change mount namespace of snap "brave" according to change mount (/snap/gtk-common-themes/818/share/icons/Suru /snap/brave/44/data-dir/icons/Suru none bind,ro 0 0): cannot use "/snap/gtk-common-themes/818/share/icons/Suru" as bind-mount source: not a directory

It looks like snap-AppArmor integration issue.
