Android SDK no log for Emulator

Question

I want to create my first application in Android SDK.

But when I want to start the emulator, I have this error message : "The emulator process for AVD Pixel_5_API_15 has terminated."

I tried few android phones version but I have always the same issue : "The emulator process for [...] has terminated."

But the real probleme is : I have no logs !!

In the "Event log" window, there is any message from the emulator process.

I was looking in the settings of the event log, but the Android Emulator is enabled in the notifications.

So I don't know what's my problem ...

How can I see the log of my emulator ?

Thanks !

EDIT :

Thanks Adinia, with your link, I find the log, and here is what I get :
