I tried to upgrade to Ubuntu 19.04 through the software-update and it kinda worked well this time, except that it failed that a menu is not installed properly and issue with that and it'll start rollback to the old version.
I thought it's going to be okay and it'll rollback and nothing happened for an hour, so I restarted the system. Now I am in Ubuntu 19 and all the applications work fine but the problem is I can't access the dash menu (start menu).
Every time I try to open dash or press the window key, the desktop environment crashes and pushes me to the lock screen. I am not entirely sure what's missing here and don't know where to look up for the cause.
Let me know if you need me too look up for the logs somewhere and paste it here.

or something else). If it didn't complete; I'd login to a terminal, andsudo apt dist-upgrade
to see if it'll continue & complete). If you didn't upgrade from 18.10; you're outside of tested & supported upgrade paths anyway.sudo apt dist-upgrade
it shows 0 upgraded, 0 newly installed message.sudo apt update
(and look at the output as it scrolls to ensure 'cosmic' [18.10] lines are gone, with 'dingo' [19.04] lines having replaced them), thensudo apt dist-upgrade
again expecting 0 to upgrade (but just to be safe). The next likely cause that comes to mind is if you've added other gnome extensions (18.10 or before) that aren't compatible with the newer gnome release; as if these cause a 'crash', gnome-shell will exit & you're returned to login screen.
