Why Device Manager don't open?

I'm working on the Flutter project. After I updated the version of the Android Studio when I click on the device manager to open my devices it doesn't show. I don't know what should I do?

At the first image it's gif image to explain what I mean.

I put the second image to show current version (Bumblebee).

IntelliJ (Android Studio) wants to know what kind of project you have to show the right menus.

1. click left in file tree on the root node (project name)
2. MENU -> FILE -> PROJECT STRUCTURE
3. select left MODULES
4. hit + button to add ANDROID
5. hit OK Button
6. top of the root node (project name) select PROJECT... to see your old view

press shift 2 times to open search everything and type "Virtual Device Manager".

I also face this issue with new Update of Android studio. So i just got a solution..

Go to the Search icon on the top of Right Corner or Press Shift Button twice to open a Search window. And Search Virtual Device Manager then you will eaisly got your Device Manager.
