If you have the Stacktrace Utility window open and switch the build target to something other than Android, the window will fail to load. Ideally it should display a message like the main Logcat window ("You need to switch the build target to Android") when this occurs.

1. Open Unity
2. Open the attached Project
3. Switch the Build Target to Android
4. Open the android logcat window
5. Open the Stacktrace Utility window
6. Switch the build target to Standalone

Expected Result:
The Stacktrace Utility window displays an appropriate error message stating that it cannot be used without setting the build target to Android.

Actual Result:
The window fails to load.

Tested on Windows.

Occurs on package version 1.0.0
