How to resolve when Logcats stops working in Android Studio?

In my case in Android 2.2, for some reason, Firebase was selected by default in the dropdown box marked above. So logs didn't drop. I just needed to change it to No Filters

Hope this helps someone.

I finally got the log to start working again.

I did some updates in Android Studio, mostly just the repositories, but what I think was the real solution was to turn off my phone and have it turned off for about fifteen minutes. After that, the log started to work again.
