Infinity loading devices in Android Studio

Issue

I saw this picture, when open Android Studio few minutes ago (I haven't done anything specific before) - studio infinity trying load device

Please, tell me, how I can solve this problem? If you need some data, I`m ready to take it.

Edit: I tried invalidate cahes and restart ide, it isn`t worked

Edit2: I tried start emulator and get this message

Solution

My problem solved [this question]. I just open terminal in sdk-directory, write "adb start-server" and delete all adb.exe in task manager. 1
