Unable To Toggle Full Screen

Hello, I have been having an issue with toggling full screen. I have read through the docs and everywhere I go I see nothing but

Screen.fullScreen = bool

Should be easy! Well, I have been doing this and have tested, both in builds as well as in the editor via debug messages. In neither case does it ever exit full screen nor does it ever state that Screen.fullScreen is false.

I have seen around some forums that the Player Settings could also be the source of the issue so I took a look. Currently my Full Screen Mode is set to Full Screen Window. However, I have tried other modes as well with no luck.

I was hoping that someone could please help to point me in the right direction. Thanks so much!
