Connected device [OFFLINE] - Session 'app': Error Installing APKs - existing connection was forcibly closed

Question

When I trying to:

I after build my device disconnect automatically and Device status [OFFLINE]

2:41 PM Session 'app': Error Installing APKs

And also sometime I found event log like this in Android Studio 2.3:

2:27 PM IllegalStateException
                Android Studio could not interpret the results of the Gradle build correctly.
                You may be able to recover from this issue by pressing 'Run' or 'Debug' again.
                Please file a bug at b.android.com including this message and your idea.log (Help | Show Log in ..).

    Session 'app': Error Launching activity .

Already Tried.

• Disable Instant Run feature from settings.

• Perform a clean build and run again.

• Terminal window = start and stop adb server using this command "adb kill-server" and "adb start-server".

• Enable and Disable USB Debugging.

Note: If I restart my device and Windows PC then it works but I can't restart every time so any one have better solutions for 'app': Error Installing APKs issues.
