I had a similar issues, when i would launch forge the launcher would close and then within in a second, i would get exit code: 0 i deleted .minecraft and reinstalled Minecraft and it worked. I don't know if it would work for u but it worked for me, just make sure to back up ur worlds in a folder/ flash drive

I double click on it to open it and it just creates a txt file but doesn't bring me to the page to install it
