I managed to solve my problem by renaming .config and .cache as explained here https://askubuntu.com/questions/831569/unity-is-broken-launcher-menu-bar-dash-disappeared-unity-reinstall-doesnt-w/831570

To sum up:

(1) I did a security update on March 2nd then did a reboot on March 3rd
(2) Both the launcher and menu bar disappeared in my main session
(3) .Xauthority was owned by root, I do not know since when and if it caused any issue
(4) .config and/or .cache were likely corrupted, I do not know if this was caused by the update
