Android studio 3.6 can`t open emulator

Background:

I am using android studio 3.6 as my IDE for flutter development, the problem below only happening when I use android studio with flutter, in native android development it's all fine.

The problem:

Sometimes my android studio will not be able to detect my emulator and in order to run something on it(or even open it), I will need to open the Avd manager and run it from there (It is working sometimes).

Visual explanation:

1) What I meant by will not be able to detect my emulator... looks like this:

2) And What I meant by I need to open the Avd manager and run it from there looks like this:

Question:

I am using the stable version of android studio, why this is happening and can I make sure that android studio will detect the emulator every time without going to the Avd manager

Updating the android studio to 3.6.3 version solved the problem.
