I am stuck a whole afternoon trying to run again my small Android/Kotlin application in Android Studio. The message pasted on this question topic suddenly nocked me down.

I have done these tentatives:

1 - cold boot (On Virtual Devices screen > Actions > Cold Boot Now)

2 - I deleted my previous Virtual Device and I downloaded a new one (Nexus One)

3 - I followed all steps from [other stackoverflow answer](https://stackoverflow.com/a/49345049/4148175)

3.1

```
cd C:\Users\Jimis\AppData\Local\Android\Sdk\platform-tool

adb kill-server
adb.exe start-server
adb devices -l 

```

3.2 

deleted plataform-tool and redownlowaded it from [SDK Plataform](https://developer.android.com/studio/releases/platform-tools.html#tos-header)

3.3

restart computer

I am completely stuck.

Something called my attention: why so many PIDs to port 5037. See bellow that initially when I started Androdi Studio I had only 3 and after I tried debug my application I got a lot more.

in case it is relevant I just aupdated to Android Studio 4.0 and same issue.

Reading a lot on stackoverflow I reached this [other issue](https://stackoverflow.com/questions/58152237/android-studio-emulator-vk-version-1-1-check-failed)

I tried added advancedFeatures.ini in my C:\Users....android with 

```
Vulkan = off
GLDirectMem = on

```

I don't know exactly what I did but I tried it anyway and I am still getting same issue. In this same stackoverflow discussion I noted someone talking about hyper-V. 

In case it is relevant, I have turned off Hyper-V some time ago in my Windows 10 because I had to use VirtualBox for other reasons (OpenShift/minishift). I don't think it has relathionship with my issue because until 2 days ago I had not such problem with port 5037. BTW, I am curious: does Androids Emulators depend on HyperV somehow?

\*\*\* edited after Jacob's comment

Microsoft Windows [versão 10.0.18363.836]

1) Before I started Android Studio I had no connection to 5037 as expected

C:\Users>netstat -ano | findstr "5037"

2) Then I started Android Studio and I see at least three connections to port 5037. 

```
C:\Users\Cast>netstat -ano | findstr "5037"
  TCP    127.0.0.1:5037         0.0.0.0:0              LISTENING       11880
  TCP    127.0.0.1:5037         127.0.0.1:54602        ESTABLISHED     11880
  TCP    127.0.0.1:54602        127.0.0.1:5037         ESTABLISHED     348

```

3) And when I click on Debug app (shift + F9) I get two messages errors on left bottom side of Android Studio 

```
Emulator: emulator: ERROR: AdbHostServer.cpp:102: Unable to connect to adb daemon on port: 5037

Emulator: socketTcpLoopbackClientFor: error: fd 56668 above FD_SETSIZE (32768)

```

and a lot of connections with numerous TIME WAIT. It seems so weird to me.

```
