Unity Won't Build My Project

Hello, I am new to Unity and I have just finished my first game. I now need to Build the game to PC, Mac & Linux Standalone (specifically Windows), but Unity is not building it. No error messages or completed messages are shown and the build is not in the location I told it to save to. Lastly, when I try to build the game, the window that pops up only lets me choose where to save it, not what to name it as. I am using Unity version 2019.2.11f1. Can someone please help me?

1st of all make sure your “scene” is added in “build settings” (top of the box/menu), and a check mark next to it, as if its not, drag and drop it into the box/window, or you wont be able to make a build.
