Can you help me figure out why I can create a exe document but not a apk document?

Hi there. I have an issue that I am facing. I have a game that I am trying to put on the Android market and I can create an APK file, but it fails to open when sent to my Android phone.

The unity engine is saying the following error "Could not extract GUID in text file projectsettings/projectsettings.asset at line 44"

What do I need to do to remove t$$anonymous$$s error after the build to create a successful build? The game works fine in the editor and works fine as a .exe file, but not working as a APK. I have the latest SDK and the latest Unity update of 5.6.0f3.

By the way, the error message for the project settings did not occur until I have made an update with Unity and the APK still would not load on my phone with an error message of "Unfortunately, (game name) has stopped." The APK is not loading on my phone with Unity 5.4.2f2 and 5.6.0f3 update.
