Android Studio device dropdown stuck on "Loading..."

So after some pause in mobile development, I decided to get back to it and so I decided to upgrade Android Studio to v3.3 as well (Windows x64) along with Flutter and Dart. Now my problem is that when I click the device dropdown <no devices> in the toolbar, it displays this:

And when I move the window around the loading item stays in its fixed position until I randomly click somewhere.

Despite this, I can still launch an emulator using the AVD manager, though it won't connect to the application because of this bug. The weird thing is, I also installed Android Studio on my new laptop, but there it does work, so it's probably a fault in my settings.

I've already filed a bug report, but does anyone know a fix or workaround to this problem? Thanks in advance!

Try reinstalling Flutter and/or resetting the Flutter SDK path under "File > Settings > Languages and Frameworks > Flutter".

I spend time on this issue i got solution

Delete platform-tools

C:\Users\ (computer name)\AppData\Local\Android\Sdk

from this path

And download new Platform Tools from this site

then unzip and paste it on this location

C:\Users\ (computer name)\AppData\Local\Android\Sdk

File -> Invalidate Caches / Restart and click Invalidate and Restart fixed it.

• Make sure you have Power Shell 5.1 or greater (You can run this command to check $PSVersionTable.PSVersion Update Flutter, Dart and Android studio then restart Android Studio

This worked for me:

1. Disconnect all physical android devices connected to the computer
2. adb.exe disconnect from sdk\platform-tools folder
3. adb.exe start-server from sdk\platform-tools folder
