I have no menu bar on Evolution, main window, can I, renew or what? without losing anything?

I need to restore the menu bar, without losing any file or E-mails.

If you disabled showing the menu bar, you can hold down Alt to make the menu bar show. Then enable it again in View > Layout.

Thank you, but i fixed it yesterday, but i think that would not work, there is no view, the whole line was not there.
I fixed it with gsettings set org.gnome.evolution.shell menubar-visible true.
that worked
