Could not connect to remote process. Aborting debug session. Attach Debugger OK button

When I try to debug the app, the emulator sticks on "Waiting for debugger". Meanwhile, in the debug tab, it can be seen that AS is "waiting for application to come online". But after a moment shows "Could not connect to remote process. Aborting debug session". As a further attempt, after running the app normally, I try to "Attach Debugger to Android Process". "Choose Process" dialog is opened and the process on emulator is shown correctly, but the OK button is grayed out!

I read and implemented all possible solutions in the web without any success. Still i encounter "Could not connect to remote process. Aborting debug session." This happens on all apps with all emulator and real phones.
