One of my account can't login to google play
Google is in the process of switching to Gamer ID's. They've been rolling this out for around 6 days now since they announced it (they're further moving away from Google+).

Until you get the notification to choose your Gamer ID (or go into Play Games and receive a popup notification to choose yours), you could temporary downgrade your version of Play Games.

First, look version of your Google Play Games on Setting > App > Google Play Games.
Memorize the last 3 number (mine 038)

Second, download older Google Play Games from here (the last 3 number)
http://www.apkmirror.com/apk/google-inc/google-play-games/google-play-games-3-5-17-release/

Third, uninstall your current Google Play Games, and install the downloaded Play Games.

Good Luck.
