Running it manually worked! But is there anyway to get the file working, or maybe a .bat file just so I don't have to go into the console to launch it ever time? But still, thanks for the help!
Edit: Nevermind, I ended up remembering how to make a bat file that start it again! And thanks for the help dude!
I've decided to start up a forge server for my friends and I again, but as the title says the file won't start up. I had one working before but I've since completely deleted the files for those as at the time I didn't think I would use the server again. However now the forge server file won't start up. The vanilla minecraft file for the server starts up perfectly fine. I don't know what is causing this problem, but I've tried using an older version of 1.12.2 forge and the file still won't start up. The more peculiar thing is that the file used to start up. This seemingly all happened when I was trying to add more RAM to the server so it wouldn't be laggy.

Note: I do have the eula set to true as I know people always mention that with server problems
