Random Project Crash While Coding *Code Included*

So, i was editing this script and randomly crashed my project apon saving. Once i tried loading my project again, it crashed. I then deleted the scene through the project folder. I made a new scene and then put my "Menu" script on an empty. I then clicked play. once in game, i clicked p to open up my menu and it crashed my project again. Also when i add my "PlayerStats" script to my new player it crashed right away. I have no idea what kind of code would actually crash my project.. If you would, please read through my code and see if you can figure it out. Thank you very very much! :)

"Menu" Code: static var paused : boolean = false; var pauseMenu = Rect(10,10,1500,850);
