How can I stop forge installer from opening with notepad. I tried redownloading it and it still opens with notepad. How can I stop this from happening?

My forge 1.12.2 shows up in launcher and the tap shows up when I launches at the bottom of my screen. The game itself doesn't pop up on my screen. When launching forge again, it will just say that a game is already there. Can someone please help me solve this problem? I have already tried searching for multiple instances of minecraft using task manager, finding nothing.
