I go itno ‘build settings’ in the Unity3D menu and click on ‘player settings’ but nothing happens. I need to open player settings so I can set the correct bundle identifier…
Also make sure you have an inspector tab open. Go to Window > Inspector. The PlayerSettings appear there.
try going to the player settings via
Edit → Project Settings → Player
if it still doesn’t open uninstall and reinstall unity .
Or that the inspector is not locked ( little lock icon on top right )
Ok, I figured it out. It opens project settings but in a minimal window, click to open the player settings from the build windows for example and note a tiny vertical line appearing somewhere on the screen, put the mouse near it to scale it up…
check android plugin if missing then install it other wise override on it. hope it’s help full.

I had same problem (in Unity 2019.2.12) and I solved in this way:
Go to Edit-Prefences-External Tools
Uncheck “JDK installed with Unity (recommended)”
Uncheck “Android SDK installed with Unity (recommended)”
Uncheck “Android NDK installed with Unity (recommended)”
//
Now, Browse for JDK,SDK and NDK and select these installed folder.
That’s it! You can go Edit-Project Settings-Player Tab now.
//BONUS//
Let’s make easy for SDK,NDK, JDK:
Download JDK here: https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Download SDK here: Download Android Studio & App Tools - Android Developers (you dont need download Android studio you can download just SDK from “Command line tools only tab”)
Download NDK here: NDK Downloads | Android NDK | Android Developers (I have r16b I dont know that Unity support which version but r16b okay)
I had the same issue and what i did was click on any other platform and use the bundle identifier of that particular platform and i dont know what triggered it, when i went back to android, the player settings appeared as it usually does.
PS i know its too late for the person who posted this question, but for anyone who comes along this problem, hope this works!
Hi all 
try this :
- Window > Layouts > Default
- You should get this msg in console.
